Getting up for school

Hi everyone! Is anyone else experiencing issues getting their 4 year old to school in the morning? At night my daughter asks us if she has to go to school the next day. If we say yes (she only goes 3 days a week) she gets upset. This is the first time shes been in a school setting but she has been going since late August! She cries and says she doesnt want to go because she misses us. By the time she comes home she seems fine. Today was especially hard because it was her first day back after Spring Break. I tried to explain that all big kids (like her cousins) go to school. Does anyone have any tips that may help ease her mind and make it easier to get her out the door in the mornings?
