It is way too early to be saying she doesn't like coming to your house! It is a big adjustment and it sounds like she is doing quite well. I have a 2 year old who started with me 7 weeks ago and she is still having a hard time and clings to her mom every morning...she knows and I know that it isn't because she doesn't like me or the things we do..she is just not used to being here as opposed to at home. Maybe you could have a chat with the parents about the normal process of adjustment and that it takes kids time to feel secure in their new environment.
