I was the parent of the difficult child at one point. He was very happy to be at daycare, he loved the other kids, but he didn't understand how proper social rules worked. Our daycare provider was a wonderful woman, and was kind and incredibly patient with him. That being said, though, we worked with her every step of the way. If he hit another child, or couldn't calm down, he came home. That was put forward by my husband and I. He had a very strict set of rules at daycare, and he came a long, long way while there. I truly believe it was our cooperation that kept our son in daycare, and he benefitted greatly from it.
