For instance, how long should a play date last? My daughter is 9 and I want to let her invite friends over to play in the summer hols, how many hours is normal to have someone else's child over. I had a child over last year and her mother said "il pick her up at 5" which meant that I would have her child for 6 hours! Is this normal? I thought 3 hours is enough? Also, my daughter's friends from school all have sleepovers but I think that 9 years old is too young so won't allow mine to participate aibu?
