We have a very recent diagnosis of hypermobility/hyperflexibility and low muscle tone in my almost 4 year old.

He has it quite badly and scored off the charts for internal hip rotation and it turns out he has no core strength. The physio is astounded that he has reached the milestones he has, and perseveres with so much, even though he clearly is doing it tough.

What has hypermobility meant for your older child? Is school that much harder when you struggle to sit (especially with so much hip rotation) because your core is weak, and you have to lean on your elbows to hold your head up?
He can never sit still now at 3, almost 4. I never knew it was because he physically can't.
And what about tiredness and school and kinder? Is it obvious that they can't keep up?

I feel really sad for my boy. Sure, bending your thumb backwards is a great party trick, but not being about to stand properly because his muscles are so weak is a bit more serious.

Everything I read is a so negative. When we strengthen him up, will he be able to keep up with his peers at kinder next year? Or will these things always be a struggle?
