S.S.
make sure you ask her teacher how long she is crying after you leave. if she is crying for a long time, like over an hour or on and off through the day, you may have to find another daycare situation because she is obviously uncomfortable in the current one. but if she stops crying ten to 20 min after you leave, all you can do is give her a big hug and kiss, say good buy and leave quickly. the longer you try to pacify her the harder it will be on both of you. you can always call the daycare about 20 min after you leave to check on her. most likely they will say that she is playing and doing fine.
