my daughter 3 years 3 month she suddenly started refused go to school before form day One she was gone happily. 2 weeks happened she didn't want to go to school

A. Well actually this is common sometimes kids are very happy to go to a new place initially but then when they see that they have to stay away from the mother they start having separation anxiety which is common and sometimes also is a place where sometimes it gets cooled for being mischievous and also they don’t like it they take it to their heart as they’re very sensitive so try to do regular counselling and check in the school of something has happened lately
