RoyalUk thanks for sharing your story. He will be taking off his brace for PE and he also plays basketball out of school so will take it off then also so that will be his 4hrs for the day. He's having trouble at night as it's very hot but next week he gets some holes drilled into it so his skin can breath.
~Kaz~ he will need to wear it until he is 21 so a very long time.
Thank you all for your advice.

Regards,
Dianne
