How can my brother in law and sister in law be so stupid? I told myself that I would never let them babysit for me, but my baby was asleep and needed my mother in law to run me to the house really quick. We told her we would be right back. We was gone for 10 minutes. They felt the need to leave for church before we got back. So they took my daughter with them. But here's the thing. They didn't belt her carseat in. My brother in law thought that if he went 10 miles per hour that would be for one of them to just hold the carseat. When I got mad they keep telling me she was fine. Never will I ever trust them again. Rant over.
