In the beginning, my MIL helped a lot (including during my first pregnancy)... she also kept her word.

For the past couple months, it has seemed like something seems to come up every time she said she will do something like keep my daughter overnight. She calls me up usually about ten saying blah blah came up.

My relationship with her has never been good but lately it seems to have gotten worse. I don't know what to do or even if I should care anymore.
