Hi C.. ((hugs))
I have a son with autism and also has hypotonia. OT really helped him. Since she is only 15 months, is she also getting early intervention?
She' should be able to get it.
She'll catch up, it's a matter of time.
My son was in OT for a yr before testing out. He's still clumsy but we put him in swim and gymnatics to help. She is so young, but getting her into programs later on will help too.
Best of Luck
