I was a assistant director of a Day Care for quite a few years. Some children have trouble with the drop off and some don't. Sometimes when a parent prolongs the goodbyes it is harder then if they bring them in and say their goodbyes with a kiss and leave. Some do cry for a few minutes after the parents drops them off but most are off playing as soon as mom or dad gets into the car to go. Ask the teacher how long she cries after you leave. If it is more then a few minutes, find out if a child has been mean to her or is something changed, like a new teacher or if her friends from before decided to play with someone else. Chances are she is learning to control the situation with the extra kisses and such and she misses you when you aren't there. I remember one little boy who carried on horribly when his mom dropped him off with the more kisses and no momma don't go, but when his dad dropped him off it was "bye daddy, love you" and he was off playing.
