Our daughter was also diagnosed with hypotonia at about 9 months of age. She had 7 physical therapy treatments and reached her motor milestones within normal ranges. Our PT was great, and being a PT myself I would highly recommend it. The home therapy is a way of teaching you things to do with your child to give them maximum benefit. Our daughter is now 19 months, and while she will always be low tone-hereditary-she is totally "normal", running, climbing, galloping and starting to jump. I credit the early intervention she got with her success. Continue to be an advocate for your child, give him your love and support and best of luck to you!
