My little girl would like to have her first sleepover with a few friends. She is turning 8. She has two older brothers, 13 and 15. When discussing the sleepover with my best friend she has expressed concerns that it was inappropriate to have girls that age in the house when there are teenage boys under the roof? She can't really give me a reason why she thinks it's not wise, just a feeling. AIBU in thinking this is perfectly fine as there will be no sharing of bedrooms or space at any time? The boys will be holed up in their rooms and the girls plan to overtake the living room.
