I don't consider us to be a 'larger family'. I've just had DC3 and he only takes up a bit of space . we will most likely have one more DC and that is when I'll face being a larger family.
Anyway, I have recently had my first situation where a friend obviously doesn't want us to go and stay. On occasion I have been to visit on a week day afternoon and then left the following day. When I suggested doing this again, she seemed to prefer meeting elsewhere for the day. That's fine and I understand.
Other friends also joked that they needed a big make shift table in their garden to fit us all in.
I just wondered how many children you had before you began to notice that people found it a problem for you to visit. Will 4 DCs make us the family that never gets included in things.
