My 4 year old refuses to go to play school and cries every day when I leave him in playschool. Any tips to improve this??

My daugther feels heavy to say byebye to me each day when she goes up to school bus. For me, I just acknowledge her feelings that she misses me and I miss her too. Like adult, when our husband goes overseas for work we will feel the same way too. Unless you feel that there was something happened in school and causing her not wanting to go to school, you should talk to her teachers to understand what is going on or has happened e.g. bullies etc. For my daugther I know she is very happy and enjoys her school and thus, I know she just feel hard to say byebye to us.
