Have you taking him to the doctor he might not can control it or there might be something he is going through with school.My girls still wears pull ups to bed and if they keep them on they keep using them.

My son most of his accidents when he's playing somewhere else, or outside and doesn't want to give up the toy, spot, or game for fear that it won't be there when he gets back. He tried to put it off to the last minute and ends up wetting himself. It doesn't happen often but It does happen in groups.
Tell you son it's okay to go to the bathroom. Tell him that he can give his toy to the teacher and she'll watch it until he's done. Maybe that's the trick. ???

good luck!

I would try to work with the teacher to try and ask him about potty breaks more often. Are they giving appropriate breaks at the school? Does he never have any other accidents outside of school?

I have taken him to the doctors and they said that he might be too lazy so I am going to try and talk to his teachers again at school as the last time I spoke to them I got no joy

My four year old has been potty trained since he was two. All of a sudden he stared wetting the bed a lot. One day he was at a friends house while I was runnig errands and she called me to tell me he was just sitting on the sofa and he wet his pants. I took him to hopital ER immediatly and they told me he was having seizures. We did all kinds of tests to find out what types of seizures he was having. So, you may want to check that out. I know when mine wets the bed it's because he has had a seizure. As a matter of fact he wet himself at school yesterday during nap time.

I use to work in a pediatric urology clinic and the advice to go to a doctor was right on, but many general practice doctor don't have the equipment to fully evaluate this problem. Many kids have this problem when they are constipated. Check the school bathroom, schedule for visiting the bathroom, any fears about going, ect.. Check with other parents to see if this was a problem with their children. I volunteer in a pre-k class and we have to make sure the kids have gone to "try" multiple times a day: 8:15, 9:30, before lunch, always after lunch which is over at 11:15, 1:30, and before dismissal at 2:30. It seems like a lot but it works. Having a bathroom in our classroom helps. They just get up if the door is open. We have them wash their hands at a sink we can see to make sure they wash. Only had two accidents since Sept..Best of luck.

Along with the doc advice which I agree with, try to figure out if there is something bothering your son. I do know that my son is more likely to have an accident if something is bothering him. Either he may be having an issue with homelife, or a playmate/classmate difficulty can show itself in accidents. I would try to get him talking about school and life in general to see if there is anything there. I like to ask my 4 yr old what the best part of today was and the worst part before bedtime. It can give you insight into their world especially the worst part one. It kills me when it's that I yelled at him and I am very sorry when I lose my temper and tell him so. Good luck.
