My 3 year old daughter has just started her school a month back. Due to holidays, weeknds or at times she was unwell , she didn't go. Initially she cried a lot but gradually the crying has decreased. She still says she don't want to go to school. Also she has become possessive about her school bag, bottle and other things. She won't leave her bag ever in school which is restricting her physical activity. If it's coloring, or any sitting activity, she will keep her bag next to her. Also she is not interacting with other kids in class is this behaviour normal?
