In my five years of daycare I have had to terminate 3 families. 2 were duie to the parents and not the child. One refused to sign my contract when I made some changes etc. He used to make sarcastic comments etc and the whole thing became uncomfortable. You need to be able to work as a team, parents and provider and if you can't and don't have good communication and you have done everything you can then maybe it is time to say good bye.
