I am sorry you are feeling hurt. It is very hard to lose a daycare child, especially one that you and your family clearly care for deeply. Am I to understand that she normally doesn't come in the summer anyway? I think that three months notice is plenty, personally.

As for the gift, it may show that she doesn't know your personality very well, but I certainly wouldn't be insulted by any gift I received from a parent.

Good luck filling your spot. You have several months. I hope you find a nice family to replace this one.
