I have 2 sisters I look after age 5 & 7. They come 4 days a week and in the holidays they have been driving me mad with their arguments which usually start with "she's not letting me have ideas!!!" I have lost count of the number of times I've said "you can have as many ideas as you like but your sister doesn't have to do what you say!" Back to school later this week - thank goodness!! So - what arguments drive you mad??
