do you invite her in for a cup of tea (even if you've never really met) or do you simply return her dc? I'm just starting out with playdates for dd1 who is in reception and wondered what the "done" thing is. On one hand I'd like to invite the mothers in for a cup of tea to get to know them. On the other, I've usually just got in from work and it is the dcs bedtime. I don't want to be seen to be rushing the friend/mother off if the usual thing to do is invite them to stay for a chat at pick-up time.
