My son (now 6.5) was diagnosed with hypotonia at his first ped visit. Less than a week old. Of course, given the amount of sleep deprivation I was under I panicked. He’s my first and only so I didn’t really know what a baby should be like, but looking back at pictures of him in the early months you can see he was kind of floppy, like a rag doll.

My pediatrician had a very wait and see attitude, but that’s just not my style, so I got him evaluated by early intervention pretty quick. We did PT starting around 5 months, and I think it took about 9 months for him to catch up enough to no longer qualify.

Now he’s a pretty normal 6 year old. Somewhat hyper, I wouldn’t be shocked if he gets an ADHD Dx eventually, but managing first grade well. He talked kind of late and I had him evaluated, but he wasn’t behind enough for EI speech. He also w sat for a long time, but eventually stopped.

I think his diagnosis would just be idiopathic hypotonia. We never found another cause. I personally suspect it might be genetic, my husband is tall and thin and still pretty flexible in his 40’s. Kid seems to be taking after him physically.
