Tips for reuring my pre-schooler please?

I know how you feel ... my little girl went to a childminder and used to cry when I left her. There were a couple of things I did to help her; one was she has a favourite rag doll that she used to take everywhere with her. Just as I was dropping her off at her childminder I would hug the doll and say I was putting my love inside it so she could hug it when she missed me. Also I would wear a locket that has a picture of her and her brother in, so I would always be carrying a bit of her with me all day. These little things helped make the parting a bit easier. Separation anxiety is totally normal in young children, but it is very hard being faced with it day after day. I hope she settles down soon, and you know that she is fine after you leave her - it is just the saying goodbye that is so hard!
