My friends little daughter has hyper mobility, hypotonia, global development delay of a unknown origin.
She was (is) basically one big flop. Pick her up, she's like a rag doll, limbs just hang. She's had physio once a week, and had the little kickers shoes, nd the standing frame which she used for a hour and half from a young age. She could not weight bare on her legs, they are tiny in proportion to her body size, she's nearly 3 now and is size 3-4 in shoes.
She would roll about every where, and old sit un supported by about 18-19 months. By about 28 months she would be in the crawl position, and eventually started crawling very slowly, with her hands in a fist. About a month after that, she started weight baring on her feet, and would walk holding on to your hands, although her legs would be in all directions, so still very unstable, and feet old be pointing all over the place.
She crawled about for a good few months (like a baby) then went through the cruising stage along furniture and was a lot more stable.
At the beginning of the summer holidays, she took her 1st steps ever on her own. And she's off!!! She's a little top heavy (always has been), but can now steady her self, she looks a little drunk when walking!
Developmentally she's still way behind think she said 12-15 months! But this is amazing! Doctors sais she will never walk or talk!!!
We're half way through fundraising to build her very own sensory room kitted out with all the stuff that help her strive in her own home! :)
