As a former daycare provider, let me give you a bit of advice. In the AM when you drop her off, she may protest, she may even cry when you get there and are going to leave. It isabsolutely imperative that you leave quickly. Give her a hug and kiss, tell her how proud you are of her and that you love her, and leave.
I promise you within 5 minutes she will completely stop crying and she will make friends and have a good time. I've seen this numerous times, and experienced it with my son. Don't stress, this experience will be good for her!! :)
