This little girl I am concerned about is a bright, verbal, social 4 year old who does well in pre-school for the most part. However, in the last few months she has become very clingy some days and sometimes cries when being dropped off at school. Today was grandparents day and she refused to participate in the activities and insisted on having her grandmother hold her and cried when her grandmother left. She also did this clingy crying routine when her mom visited day care on parents day. Her teachers tell us that she is generally very hepful and sociable at school, has friends, and enjoys singing and coloring, etc. Is this cling needy crying stage at all normal for a 4 year old?
