I've recently started looking after an aquaintence's two children as a favour to my friend who was looking after them. I'm not a childminder but just take them and pick them up from school with my child. However, they aren't very well behaved and them being at our house is effecting my daughter. She even said to their face that she hated them and doesn't want them to come anymore! She's not usually like this but is resenting them big time. I'm feeling now that I shouldn't have offered as my own children are suffering. It wouldn't so bad if they respected me but they don't listen to a word I say and they completely trash my little girl's bedroom (although this week I've not allowed them in there). Anyone got any ideas how to make the time with them and my own children more harmonious - otherwise I'll have to let their parents down by saying I can't do it any longer. I'll feel so guilty saying I can't do it anymore after such a short time.
