My 3yr old son doesn’t want to go to school suddenly. He has been enjoying school all this while and one day just came back and refused to attend school. What should I do?

it is possible that something happened in school that triggered this reaction. it could be anything, maybe another child did something, maybe the teacher spoke to someone in a loud voice, he feels sleepy or tired and wants to be with you, or anything for that matter. 3 year olds can get upset about so many different things! like all the other parents mentioned, please speak to the teacher. and also try and say nice things about the school to your kid and see if he comes up with why he does not want to go anymore.
