Going from 3DC's to 4, did you find that 4 played together better than 3?

[MollyNollyNoo]

Just pondering really as I would love to have another...we have 3 DC's and unless one of them is elsewhere (nursery/napping/doing their own thing) they don't seem to play that well together as one of them is often left out. If friends visit and we have 4, 5 or 6 DC's in the house/garden they all get along much better.

It will completely depend on what the 4th child is like. We were lucky that ours mostly always got on very well.

Friends I think is a bit of a red herring, you can choose your friends and also they are a bit of a novelty when they come for a visit. Your brother or sister would be there all the time.
