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?

yes speak to his teacher. or talk to your son and ask him if anything happened to him in school. there must be something that happened in school that triggers this. my son happened before. my parents keep prompting him and he said 1 of his classmate bullied him. i spoke to his teacher and also get the whole story. thereafter my son is ok with school .
