DD2 (8) often has playdates at our house with a few different friends, one often stays for a sleepover. They all get on really well most of the time and I generally just let them play without my involvement. When she's on her own DD2 and I play together alot, usually a couple of hours after school and more at weekends plus outings. Just feel guilty that I don't get too involved when she has friends round, apart from providing food & drink, sorting out any disagreements and making sure everyone's happy. I do play with them when asked but that's not very often!
