Same here, DS2 discharged once walking effectively outside - which was 4y8mo. (He took his first steps at 3y7mo).
It's taken me till he was 9yo to get a re-referral, and that was only because his spins was distorting and he was dxd with kyphosis by the orthopaedic consultant.
He was seen by physio within 2 months of that, and is now about to start a course of hydrotherapy.
He's been re-referred back to orthotics by the orthopaedic consultant too.
He has severe Hypermobility, he scores 8/9 on the Beighton scale, which would be 9/9 if it wasn't for the kyphosis preventing him from putting his hands flat on the floor when he bends over because of the pain.
I've been told by the orthopaedic consultant that he is at risk of ending up in a wheelchair, his Hypermobility is so severe.
Yet once the hydrotherapy is done, I can guarantee he will be discharged again.
It's WRONG that they don't do physiotherapy based on NEED, rather than budgets.
Only those wealthy enough to PAY for physiotherapy are able to get ongoing therapy for their DC's, it seems. Which I'm not.
