My 6yr old is in kindergarten. The first half of the school year was great. He would come home talking about everything he did that day. His teacher had to miss a weak of school and during that week the other teacher told me that he would just start crying out of know where. That following week was spring break and he was fine. Since returning back to school he cries every morning and has breakdowns during the day. I asked him if people were being mean, if he is tired at school. He always just says he doesn't know and he misses us. What should I do? It breaks my heart to know he is at school and not happy!!!
