Thank you all for the kind words. I have decided after this week, I will take the month of August to relax and spend quality fun time with my own kids.
If I decide to continue I will be changing my contract to include late pick up fees, etc... I have definitely learned that Families will take a mile and walk all over you if you don't have clear policies!
I have learned from my mistakes, and at the end of all this, I will get to just have some me time, and be a mommy to my kids. I am going to focus on the positive side of things right now.
