I have been doing the school run with my friend's ds (let's call him Bob) since September. Bob's younger sibling was very poorly over the summer, lots of trips to hospital and my friend was understandably very stressed, so I offered the school run to give them one less thing to worry about and was happy to do so.
However, it's now getting close to the Christmas holidays and there has been no mention of stopping this arrangement or asking whether i'm happy to continue. Things are a lot more settled for my friend, there is still the odd appointment but the sibling is much better. Her dp is around a lot and they manage to get Bob's middle sibling to preschool and back every day. Frankly, I want to stop. It's a mild inconvenience to me in that it takes a bit of time to pick up and drop off Bob but the main problem is that Bob and my younger dc (who are the same age) keep ganging up on my older dc. Nothing major but I am constantly having to police them and it's exhausting. Plus I feel sorry for older dc who is getting very fed up.
AIBU to say I can't carry on after Christmas? I feel really bad about it as I know my friend has been through a tough time and she is always thanking me so I don't feel like it's not appreciated. Can't decide if I am being really mean or my friend is being a bit unreasonable.
