I don't worry at all when my 14mo DD is with my Mum, or even spends the night with her. But if my DH mentions his Mum having her for the night, I freak out and panic. I have no idea why. She's brought up 3 kids. Admittedly they have no manners and don't speak very well and they had an awful childhood but she's lovely now. Does anybody else freak out about their children going to the MIL?
