I know this is a similar question to one recently, but my 4 year old son won’t use the toilet at preschool. He has only been trained for around 4 months or so, was petrified of using the toilet but we finally got there, and is now happy to go pretty much anywhere other than preschool. We have talked to the child care teachers and they fill him with water to encourage him to go, take him on his own in case going in front of the other kids is the issue, we take him when we first arrive and when we pick him up, but he will hold it in all day. Come 3pm when we collect him he is absolutely busting and we have had to stop the car on the way home for him to go, or it’s the first thing he does when he get’s home. And it’s absolutely massive. I’m concerned that this may cause an infection. We’ve tried everything (sticker charts, rewards, taking toys off him etc). Any advice would be appreciated.
