What arrangements should I make with the school if my child isn't potty-trained by the time they start?

This varies by school

Check with the school, as policies vary from school to school. Sometimes children aren’t allowed to start at all if they aren’t potty-trained yet. Sometimes they’re allowed to attend half-days. And sometimes the school expects parents to pick up their child or come to the school to change them if the child has an accident while at school. It’s important that the teacher and you don’t get angry at your child if he or she wets or soils their pants. If you do, your child might not want to go to school anymore. But school is very important for your child’s development. Your child learns a lot there, and it’s important that your child can also play with other children. Your child is really trying their best. Keep practicing at home and encouraging your child. Is it really not working? Then ask for help at the health clinic. They’re happy to help you figure it out.
