Recently moved into a nice street and have always wanted to stay where folk come to the door and see if DD wants to play etc, so here we are. Small girl came to the door just now, maybe a bit younger than DD who's 8 and asked if a wee girl stays here. Well she does, but is out at a friend's just now so I said this to small child and asked how she knew about DD and where she stays (she'd seen her going past and she stays about 12 houses down) But what do you do - do you go along and introduce yourself to the mum? I wouldn't be letting DD go along knocking on strange doors (possibly over protective?) and then do you let new (potential) friend come and play in garden? Not entirely comfy having stranger's kids in the house.
