Below are snippets from my journal for Aaron when he was between 16 and 18 months old.
16 months
Earlier this week we visited a geneticist for Aaron. First we saw a genetic counselor who took our family history and asked us lots of questions and then we saw the geneticist (and the counselor guy) for over an hour. I was relieved that the geneticist took his time with us and didn't rush us. He has seen a few other families in his experience who have Beals Syndrome so that was helpful to know.
So here is what we learned. The geneticist says that he thinks there is sufficient reason to think that Aaron's gross motor delays and overall muscle weakness (ie. inability to stand, pull to stand, crawl on hands and knees, creep, and so forth) is being caused by something other than the Beals. He said Beals causes contractures of the connective tissues of the joints. It can cause low tone (hypotonia) but given our family history and the history of Beals in general, he thinks the weakness is being caused by something else. He said it might be from the Beals, but he said for now we should proceed as if Aaron doesn't have Beals (he has Beals, yes, but for the purposes of sleuthing out the cause of his muscles weakness we're going to ignore that fact for now and look for other causes) and treat him as any other child with a big head and gross motor delays. And that means he wants to run the tests they would normally do for any child with those symptoms. It's a process of elimination. And it may be that it is just a part of his Beals, but he thinks there are enough reasons to look for other causes for his muscle weakness.
So the first step will be to do a series of blood tests. We'll do them in chunks to make it easier on Aaron and because they can only take so much blood from him at any given time. It's the least invasive way to start eliminating potential problems/causes.
If all those tests come back negative, then he says we should probably think about getting an MRI and that he'd refer us to a neurologist to discuss that more. Our physical therapist seems to think the MRI is a good idea and might give us some useful information. Apparently you can have a normal CT scan, but an MRI can show something that the CT scan can't pick up. If we get to the point of considering the MRI, I'll need to find more about what type of answers an MRI can give us - what exactly they'd be looking for. I know hydrocephalus and tumors were ruled about the CT scan. What else is there? I have very limited knowledge in this area.
A final option (and last resort - and really I can't see actually doing this, but he did mention it as an option) is a muscle biopsy. It's an outpatient surgery where they take a microscopic piece of his leg muscle tissue to examine it and see what its made of. But we'll cross that bridge if/when we get to it. The MRI seems fairly likely in his future since the geneticist is guessing the blood work will come back negative. But he still wants to do them since they are less invasive than putting Aaron under for an MRI.
We're now waiting on the geneticist to fax the orders for the blood work to our family physician. Then we can take Aaron in for the first round of blood work. I'm not sure how long it will take to get results. They said it depends on the test. Some tests are more involved and take a couple weeks. Others are just a few days.
Aaron weighs 28 pounds - around the 75th percentile now and his height has remained constant since birth hovering around the 60th percentile. His head size is shooting up and up off the charts (not just a little but, but way way up). It looks completely alarming when they plot it out on the growth chart. It used to be 60th percentile until he was about 11 months old. Currently he has reached Abe's head size percentile. We'll be watching it closely over the next few months to see if it continues to rise. We're all hoping that he is just following after his dad and that his percentile will now (finally) level off and stay there. It would be so helpful to know if Abe had a big head from birth or if his head size shot up around a year too. But we don't have that info. The earliest record we have is at 16.5 months. His head size was 53cm then (assuming an accurate measurement). Aaron's is 51.5cm. The geneticist said it is most likely that it is benign familial macrocephaly BUT he think we should look into it more since Aaron has the gross motor delay/muscle weakness that Abe did not have. All Abe's mom can tell us is that it was always big as much as she can remember, but apparently no doctor took any notice of it until he was 16 months. I would think if he'd had an unusually large head from the get-go that someone would have commented on it earlier than 16 months, so I think he probably had a similar growth spurt like we're seeing with Aaron. If I am right, that would be good news.
16.5 months
We have the results from Aaron's first round of blood work. The first half of the first round, which looked at the thyroid and other blood things like blood count, chemistry, etc. (not sure really) all came back fine. The second half, the part that tests acyl-carnitines and carnitines came back normal for the acyl-carnitines and "a little low" for the carnitines. So that means he gets to have the test repeated and he gets to have two urine tests. To get urine from a baby this age, you have to use a little collection bag. Yippie! Our doctor, requested a day to do some more research on carnitines and to see what he could find about Aaron's increased appetite. So he'll call us tomorrow and then we'll go in for the blood work and I think we have to go over to our hospital to get the equipment for the urine collection. Then we'll wait another week or two to get the results back.
Aaron has gained yet another pound since we saw the geneticist so he now weighs 29 pounds. He feels very heavy to hold! He is wearing 18 months - 2T clothes now. He is getting better at army crawling and has pulled himself to a kneeling position a few times. He can say Daddy, puppy, up, mahmah for more, mama, itty for kitty, nana for banana, dahd for bread, and chee for cheese.
16.75 months
Aaron's carnitine levels were "a little low." According to the doctor it is "borderline significant" and so they are repeating the test (had the blood drawn today) and they are also running two urinalysis tests to see if his body is spilling too much carnitine into his urine.
We'll be able to tell (I think) whether we are dealing with primary or secondary carnitine deficiency from the urine tests. And it's possible his second blood test will show that his "low level" is not significant. However, if it is significant, I think it can be treated with a dietary supplement of carnitine. If that's the case, we might have an "easy" fix on our hands if the carnitine deficiency is causing his hyptonia.
Moving on. They are also running a chromosome test with the blood they drew today. Abe had a normal chromosome test result when he was a baby, but the doctors have told us that a chromosome test in the early 70s and the one they can do today are vastly different. So we'll see if that tells us anything of use.
And finally, Aaron is getting an MRI next week. Everyone seems to think this may give us some useful information. We have to deprive Aaron of food and liquids for 4 hours prior to the MRI and no milk for 8 hours prior. So basically he'll be starving and thirsty all morning until mid afternoon. We have to show up at the hospital 2 hours before the MRI to talk to the anesthesiologist and to go over medical history stuff. They said they will gas him and put a tube down his throat and start an iv. We can't seem him until after he is out of recovery. When Ada had a coil put in her heart a few years ago, I was able to see her in recovery but this is a different hospital and they said no. We also can't be present during the MRI. Grr. It's a bit different than the CT scan. I'm not sure why they don't want us around during it. If something is very wrong, they'll call our doctor right away. Otherwise we should get the results in a couple of days.
In a couple of weeks we should have the results of the blood and urine tests back and hopefully the MRI results. So we should know a lot more then.
Meanwhile, Aaron continues to improve upon his army-style crawling skills and he has successfully pulled himself into a kneeling position at the couch, in his crib, and a play table. So that's good news. He is definitely getting stronger, not weaker, which is very, very good. It's just at a very slowwww pace and he has a lot of catching up to do. His fine motor skills are great though. And verbally, he's added Daddy, puppy, up, hi (usually says hihihihihi), and mohmoh for more to his vocabulary and learned the sign for "please".
Abe and I were out in the backyard last week tossing a football around and Aaron was on the grass sitting nearby watching us. He thought it was hilarious each time we would catch the ball. He would laugh and laugh with delight. Then we started to play catch with him. Abe gently tossed the ball into his lap so he could "catch" it (he'd scream with laughter) and then he'd gently toss it a few inches back to Abe. Sooo cute! And yesterday Asher (age 3) came up with the brilliant idea of hurling himself headlong off the couch just for the fun of it. I was just about to tell Asher not to do that because he could get hurt when Aaron noticed what was going on and found this extremely entertaining. He'd crack up each time Asher hit the floor. Aaron was so amused I couldn't bring myself to tell Asher to stop. Aaron was equally amused at dinner last night when Asher started making "snarfing" sounds each time he put a bite in his mouth. Aaron started to try to mimic the sound too and couldn't have been more pleased. I think these 2 boys are going to have a lot of fun together!
~~~
Aaron is sick right now so we have postponed his MRI to the following week. We are still waiting for the results of his latest blood work and urine tests to come back. And we met with a developmental pediatrician this week and she ordered hip x-rays to make sure his hips are all together.
17 months
We got part of Aaron's blood work back on Friday. We haven't heard the interpretation of it yet though so we're not sure what it means. His total carnitine was elevated above normal this time. The part that was "a little low" last time was normal. And last time his total carnitine was normal - this time it was way too high. I don't know what to make of it. Hopefully it is good news. We are still waiting the results of his chromosome test.
Aaron is still sick though a little better. He still has a coughing fit once a night and sometimes during his naps. But when he is awake during the day he doesn't cough too much and his runny nose is less so. Hopefully he doesn't catch the fever that Asher and I had this weekend. I have a feeling that he won't be having his MRI this week, but we'll see.
~~~
Aaron had his MRI. It ended up being a 7 hour adventure at the hospital from start to finish because the MRI kept getting delayed. However, in the end it went well. Aaron was incredibly thirsty and extremely CRABBY when they brought him back from the recovery room. He downed 2 bottles of water in no time flat. After an hour he was feeling much better and much happier, but still pretty exhausted.
~~~
We met Aaron's new developmental therapist this morning. She seems really nice. We also had our PT visit this morning. Aaron took 2 or 3 assisted steps behind a push car. We had to move his feet, but he was able to shift his weight from foot to foot. This is an improvement over the last visit a few weeks ago.
Aaron, 17 months, sitting in a big plastic bowl that our therapist would gently rock to help improve Aaron's core muscle strength and balance. He liked it!
17.75 months
Aaron took about 3 or 4 crawling steps on his hands and knees. Most of his weight was on his legs but he's trying! He also managed to climb up on step that was a shorter than normal stair step. He was so proud of himself when he got up. He kept saying, "Up! Up!"
~~~
Aaron's MRI was normal!!
18 months
I took Aaron in for his 18 month well-baby checkup. He weighs 31.1 pounds (so he officially weighs more than his big brother did at the same age - he is also a mere 4 pounds lighter than his almost 5 yr. old sister!), is 34" long and his head circumference was 51.5cm. We're waiting to hear from the geneticist (hopefully this week) as to the next step. It may be a neurologist visit, it may be a genetic test, it may be a muscle biopsy that he recommends. We'll be seeing a pediatric othopedist later this summer. He has his heart checkup in August. He had his hips x-rayed yesterday and we're waiting on those results. No real changes lately in his gross motor development to report.
~~~
Aaron is one sleepy toddler. He is usually sleeping about 18 hours a day.
Yes, 18.
Here is how those 18 hours are usually broken down:
He sleeps from about 7pm until 8 or 9am each night. (It's 9am this morning and he's still asleep.)
He then goes down for his mega-nap around 10ish (sometimes earlier, sometimes later depending on his morning wake-up time).
He will sleep until anywhere from 1pm to 4pm. Most days I'd say he wakes up around 3pm, giving him a 5-hour nap.
3pm coincides with when Ada and Asher get up from their rest time in the afternoon (1-3pm). So I wonder if he wakes up at 3pm because of the increased noise in the house.
He eats a late lunch, plays for a bit, has dinner with us, plays some more, and then bedtime.
On days when we are out and about and he can't get to bed for his nap in the morning, he will completely crash by 1pm no matter where we are and then sleep until 6pm or so, eat dinner, and then go to back to sleep around his usual bedtime.
This past Friday we had appointments for haircuts in the morning so he didn't get to go back to bed and when we got home we kept him up and fed him an early lunch because he had a therapy appointment at noon. We started his nap at 1:15 but we had to wake him up for another therapy appointment at 3:15. A 2-hour nap is nothing for him. Later that evening we had dinner and ran errands all evening and he didn't get to bed until about 8:30 - very late for him. As a result, he slept until 12:15 the next day when we physically woke him up to have some lunch since he slept through breakfast. There's no telling how long he would have slept if we hadn't woken him up at 12:15.
All 3 of our kids have been big sleepers. Asher needs the least amount of sleep but still he sleeps a fair amount (about 12 hours at night and usually a 1-2 hour nap in the afternoon). He can miss his afternoon nap and be fine though. Ada (5 now!!) used to sleep a great deal as an infant, but at 18 months she was sleeping about 13 hours at night and taking one afternoon nap of about 2 or 3 hours. After she had the coil placed in her heart to close the PDA when she was 2.5 years old she needed less sleep and had more energy in the daytime. Currently, she sleeps for 12 hours at night and does not take a nap, except on very rare occasions.
One theory I have about Aaron's need for so much sleep is that maybe because his muscles are weak he needs that much sleep to let his muscles recover. We are seeing a pediatric neurologist later this week and we will discuss Aaron's sleep issues with him and see what he thinks. I'm wondering if it might be better for Aaron if I woke him up at lunchtime (noon-ish), let him play for a bit, and then put him down for a second nap, woke him up again for dinner, let him play and then put him to bed. It would hopefully shape his sleep routine into a more normal routine and hopefully also give him more opportunities to play and exercise his muscles durnig the daytime. This mega-nap emerged late this winter. Around 12 months he was taking 2 naps a day. So I believe he is actually sleeping more now than he used to.
Certainly, one would think that the amount of sleep he gets is contributing to his weight gain. I don't feel that he is eating an unusual amount of food. He eats a good variety of foods, does not eat junk food, doesn't drink juice and he's getting very good at communicating when he is all done by signing and when he wants more food. But since he sleeps so much he isn't burning as many calories. And when he's awake he isn't running and climbing like most toddlers his age. Aaron is still army-crawling and scooting up into a kneeling position and standing only when we assist him.
At his 18 month checkup last week he was 31.1 pounds - a full 9 pounds heavier than he weighed just 5 months ago. The doctor said we may have to use calorie restriction if he continues to gain at this rate and he wants him to come in for monthly weight checks.
18.5 months
Guess who is pulling to a stand? Aaron! Hooray! Last night it just all clicked. He pulled to a stand at the couch nearly a dozen times yesterday evening. With each time he was more sure about it and quicker than the last time. On Tuesday he did it for the very first time by digging his elbow into Abe's leg (who was seated at the couch) and pulling to a stand using mostly his upper body strength. Then on Wendesday night we were about to give him a bath and he crawled into the bathroom and then pulled to a stand at the bathtub.
Then later on yesterday evening, just to keep the developmental ball rolling, Aaron also took nearly 5 or 6 crawling steps on his hands and knees!!
All of this follows our big trip to see the pediatric neurologist. The neurologist was great. He spent well over an hour with us, asking lots of questions and taking a look at Aaron. He even took time to review all the files and documentation I brought along.
So this is what we learned.
No more whole milk. We need to keep Aaron's weight under the 50th percentile so as not to exacerbate his muscle weakness. Aaron weighed 31.7 pounds yesterday which is the 97th percentile. So out goes the whole milk. He has also referred us to a local dietician to discuss the weight loss issue further. Never in a million years did I think I'd be putting a baby on a diet! He isn't fat. He is chubby. He is 34" long. He's huge, but not fat. Part of his weight is accounted for in his giant head size. They measured his head at 52cm yesterday. But at any rate, the weight gain (which corresponds with our introduction of whole milk) is making his muscle weakness worse. Basically, Aaron has more of himself to haul around. The heavier the load, the harder the work. Since his muscles are weaker than normal, he can't afford to weigh this much.
No more 5-hour naps. We are supposed to wake Aaron up from his morning nap after 1-2 hours in the morning, let him play, have lunch, play a bit, then have an afternoon nap and wake him up for dinner. Basically, wake him up to train his body into a more regular sleep pattern and to provide him with more hours in the day to play and exercise his muscles and burn some calories.
More blood work... possibly. There are several (10 to be exact) blood tests that the doctors wants to run on Aaron. I'm pretty sure we've already done at least some of them. If we have then we already know that the results were normal. If we haven't, then Aaron is in for a blood draw and we're in for several weeks of waiting for the test results to come back. One thing he wants to rule out from the tests is Rickets. It's possible that for some reason Aaron's body isn't able to properly digest the calcium he needs. He top fontanel is quite open. Muscle weakness is also a sign of Rickets. The good news, if it is Rickets, is that it is highly treatable.
Nerve EMG. If all the blood work comes back normal (or has already been done and is normal), then he wants to move ahead to a Nerve EMG. Because of Aaron's age, they would have to completely put him under. But this test would be less invasive than a muscle biopsy since there is no cutting involved. If we need a muscle biopsy, that would also mean completely putting him under. That'd be 3 times (because of his MRI in May) in a very short (I think) window of time and that makes me uneasy. If the nerve EMG is normal, however, we won't need to do the muscle biopsy.
Overall, the doctor thinks that the muscle weakness is probably just a "normal" part of the Beals spectrum. That would be the complete opposite of what our geneticist told us. So who is right? He did say that he thinks Aaron will be walking, if he continues progressing at the rate he's been going, by Christmas. That would be a wonderful Christmas present to see my baby walking!! He does think we should increase the physical therapy. He does think we should visit the pediatric orthopedist as planned next month. He does think we should wait to put Aaron under for any procedure until after we've visited the pediatric orthopedist becauce apparently the orthopedist may want to do his own tests/procedures that could involve sedation.
So today I need to call our family doctor and find what blood tests were already done. My head was whirling by the end of yesterday's visit, but I'm celebrating the fact that Aaron was pulling to a stand last night!
~~~
Five pounds. That's how much Aaron needs to lose to get back down to the 50th percentile on weight. At least that is my interpretation of the growth chart for boys ages birth to 36 months.
Five pounds doesn't sound like a lot to me, but I weigh a wee bit more than 31 pounds.
And really, since I imagine they won't want him to lose his weight too quickly if he were 21 months old, he would only need to get down to 27 pounds to be at the 50th percentile - so that's only 4 pounds to lose (assuming he doesn't gain any more).
~~~
Aaron crawled up the stairs by himself for the first time on July 1! Go Aaron!! He was shaking by the top and breathing hard though. He really pushed himself to his physical max to do it, but he was determined. It was great to see him figuring out how to move his legs and arms in the right order to accomplish it all.
He has also pulled himself to a stand now at the lazy boy chair more times than I can count, in his crib twice, and at his little leapfrog table once.
With the leapfrog table, once he stands up, he can't just stand there. He bends over the top of it, using the table for a great deal of support and stability. Most kids would probably pop up and just stand there and play with the buttons and such on the top of the table. And wherever he stands he stands with his legs bent.
Since Aaron is suddenly figuring this whole pulling to stand and crawling up the stairs stuff, I think his legs must be getting stronger. So I think our focus will shift to getting his legs straight now. We'll see what our PT says soon.
Tomorrow is our visit with a nutritionist. Aaron had more blood work done this week and another urine test. As a result he has one major bruise on one arm and a minor bruise on the other arm. :-( The big one is pretty bad. He kept looking down at his arm and crying on the first day. It'll be a few weeks before we get the test results back.
~~~
For the past two nights, Aaron has been waking up a few times a night crying. We're not sure what is going on. It could be molars coming in. It could be hunger. A couple ounces of milk soothes him. We've cut down a tiny bit on his portion sizes but not a ton. We have switched off whole milk for over a week now. Maybe he is just hungry?
And now during the daytime, after these restless nights, he is one crabby, cranky baby. I miss my sweetheart! He was throwing a fit for no discernable reason today at the hardware store. He was literally swinging his arms at me. This is not normal behavior for him. So we know he's tired. Maybe his teeth are bothering him. Maybe he's hungry. I don't know. Yet. But I do know I want my sweet little boy back!
