DS2 is 4 and newly toilet trained. He has hypermobility, hypotonia and gross motor delay. He had one of those potty chairs with the high sides which he could just about manage to get on by himself but struggled getting off. He's now decided that potties are for babies and he wants to use the toilet.
Is there anything I can buy to help him use the toilet on his own. We have a step which he uses at the sink but he doesn't have the co-ordination to stand on the step, turn round and sit on the toilet. We have tried the disabled toilet at DS1's school which is lower than ours and has child sized rails but he can't manage that either. We have one of those childrens toilet seats which stops him falling in. At the moment I'm lifting him on and off the toilet but it would be nice if he could do it himself as when he needs to go, he needs to go right then and he has had a few accidents while waiting for me to turn the cooker off or finish changing the baby's nappy. We are seeing the OT next week but I thought I'd ask here first.
