I have a good friend whos dc go to the same school as mine. When we have various after school and weekend childrens activities however, she constantly asks me - and other mums - for help dropping and collecting her dc from the activities as she is either working or down the gym. I've helped out numerous times, but when I asked for help with my dc on the very odd occassion she either refuses or initially agrees and then decides she can't do it. I really don't mind helping out others when there is a geniune need and don't expect a favour to be reciporated- but I am starting to feel as if I am being taken advantage of as it feels very one sided. I know if I say No, she'll be very upset. How best can I manage this?
