that's what he told me this morning, totally unprompted. there isn't a huge culture of this at preschool really, there are a couple of kids who have others round for lunch, but it certainly isn't the case that all the others get invited and he doesn't iykwim.
I just said to him that not all the mummies can invite children back, as x's mummy works so x goes home with someone else anyway, and y and z's mummies are expecting babies any day so it's tricky for them etc. He seemed fine with this but I'm for him that he feels like this, and scared it will continue.
Ds is very sociable and he does have friends and seems popular, we've had a few kids with mums round for lunch but invites are never recipricated - ever. so course now I'm paranoid that it's because of me - I've never been good at making friends and am scared this will affect ds.
