Posting in chat as hoping to reach a wider audience before I lose the will..
DS age 4, in reception will not use the school toilet without a parent present. He will hold wee all day, and won't drink just incase it makes him wee.
School were encouraging him to try but he can't "let go" and they aren't pushing since the new year as he has recently been crying/begging not to go to school. Currently he will come out of school, give me his bag/coat and go back in to use the toilet.
He can't be bribed or talked in to it. He was difficult and late to potty train, he still won't wipe his own bum as the poo makes him gag/throw up (he doesn't like disgusting/smelly things). I've bought books about school toilets and "invisible string" about us being connected always, I draw little hearts on his wrist, we try to understand why he won't go - "I'm scared" "they're dirty" but not true as he will go when I collect him. I've offered little picture of me to carry to the toilet. He doesn't respond to sticker charts or high value rewards like toys (although he loves toys). The toilet is in the classroom and they are free to use it whenever. He could also use it when the class is empty at lunch or use the lunch hall toilets.
School have referred to school nurse continence team, although his teacher and I feel it isn't a continence issue however they have a 4 month wait for an initial assessment and have sent me a link to ERIC, which I have looked at many, many times.
Does anyone have a child who is similar and has any suggestions? Getting desperate as I thought he would grow out of it after being the same at nursery (afternoons) but here we are!
