I realised recently that my DC are never invited to play at anyone's house, yet we have other children here all the time. We live close to school so I'm first point of call for friends who are working late, have appointments, are unable to collect etc. That's fine and my DC enjoy having friends to play.
The other day a friend whose DC I have a lot due to her unpredictable work schedule was telling me which children they had had over to play during the Easter holidays, whose houses her DC had been to etc, so I commented that mine are never invited anywhere.
She said this actually came up in conversation with some of the mums over Easter (I assume they were talking about who they'd seen over the holidays), and apparently the reason is because we never invite anyone to play. Yes, we always have children here - they play, they have tea, very occasionally they sleep over if they can't be collected until very late, they do all the usual things that they'd do if they'd been invited to play - but it seems that because their parents are ASKING me to have them, rather than us INVITING them, it somehow doesn't count as a 'playdate'. So they don't reciprocate. (I'm not quite sure how this became 'the done thing' though!)
Obviously I don't mind having the other children here, but I feel sad for my lovely DC that they never get to go to any of their friends' houses. I don't really want to start inviting even more children here in the hope that my DC will get invited back, as we all enjoy the (increasingly rare) times when it's just us. Not sure what - if anything - to do.
