I agree with everyone on this matter. You are not friends, it is her business and she is trying to not cause an altercation. You signed the agreement so you need to follow it.

I had a part-time family as well. They were all over the place and it drove me nuts. I like to plan an obviously your provider does as well. I changed my policy so that any days that were original booked were automatically paid and any days switched were considered additional days. After a few weeks of paying full-time rate the family quit switching days. It wasn't too much longer until they left. I enjoyed the family very much but sometimes think that when you are friendly with a family sometimes they begin to try and take advantage.

I am sorry you feel this way but you need to follow your own schedule and then there wont be any issues or alternatively pay for a full-time spot and then you can pick and choose the days your child attends..
