I need some advice on a situation.

My W last week was saying how she felt like the world's worst mom so she started calling everyday at 5:30 to talk the kids on days she didn't see them. It seems as though she has cycled back to her "it's all about me" persona. Yesterday when she was here with the kids she didn't do anything with them. She watched TV and took a bath. Today no phone call.

How do I handle this? Do I call her out on it and tell her how disappointed the kids are? I know she will say that I should have reminded her to which I am going to want to say that you wanted to be on your own, you need to remember things yourself.
