Hey hun i know how hard this is for you. I would liek to know the same as the others. What does the day care care givers say about how his day has been. Has anything changed in you life at all? My neice went through this 2 times before the first was because my sister had recently been arguing with her partner and my neice saw that and wanted to stay home with mummy. the second was becasue she got a new care giver that wasn't too nice, she was old and really didn't have the time for the children, after alot of complaints the lady left and she has been fine since. She loves daycare and now school.

I hope you work this out and good luck
