Hi my daughter is 3.5 year old , She is going to play school since last 1 year , but she always ends up crying when I drop her to school, this is like continued behavior , she cries a lot for little things even after returning from school and always says she does not want to go to school , if I ask her the reason why she does not like school she doesn't answer , please note I have changed 3 school but she does like any schools, also I feel she is too attached to me and cries most of the time for small things and also very clingy to me(mother) and does not want to be with others while crying. This behavior has become really frustrating for me as I am a working mom and I can't be with her all the time. With respect to health she has adenoid hypertrophy grade 4  for which she is taking medication as consulted by pediatrician . Please let me know if this is some kind of behavioral issue which will pass with time?
