Talk to your child's teacher to understand her behavior at school.. sometimes it's just a short phase as to getting used to new environment without mommy or daddy... I had a bad experience with a terrible kindergarten before (as they focus on money making rather than guiding and teaching our kids), that my kid cried everyday when sending her to school and the principal keep hinting me that my kid doesn't suit her school, and needs "special care" because I refuse to enroll to extra curriculum which cost more money than basic fees... I even noticed she stared very angrily at my kid a few times and think I didn't notice... after I change to another kindergarten, she managed to cope better and also likes going to school.
