At the primary school where my niece and nephew used to go, they had a Down’s pupil. The school got funding for the setting up and kitting out of a complete wash/shower room just for her (because she often needed changing during the day). So it really must depend on the individual child’s needs – if a diabetic’s parents can prove they need trained medical staff available, then the local authority can be approached to pay for a member of staff to be trained, or whatever. (And, I guess, often refuse, but that’s local authorities for you.)
