Another idea is to ask his teachers to toilet time him (bring him to the toilet at set times).

Don’t you worry mumma, this is very common ! He will get there. Nothing wrong with talking to the teachers and when they see he’s restless or holding his bladder they could encourage him to visit the toilet. My 6yr old has also more accidents at school as she gets distracted and want to play and probably doesn’t have the trust relationship with the teacher and teacher aid to communicate her need to go.

i have a four year old boy he has been trying the toilet training . he started then he stop is that normal . plus i have try the stickers too but he forget to tell me toilet time cause he is too busy to go is that normal

yeah i think that he just doesn’t want to miss out on the fun! remind him that he has to do pees every now and then and he will feel better while he is playing

I think you just need to encourage his toilet training a bit more. Keep him really busy but remind him he needs to go to the toilet.
The teachers at kindy say they get too busy and forget to go or they dont want to miss something or stop playing.
You might need to tell him that at school you need to do wees in the toilet like a big boy.
Normally the teachers will let you know if he isnt ready for kindy and might suggest to keep him home
goodluck, its very hard. I have twins in kindy and one has accidents every now and then because he is busy. I told him you have to use the toilet or your not allowed to go to kindy and thats helped as he doesnt want to miss out on going to kindy
