My DDs do, generally, play together a fair bit. Of course there is the normal squabbling and 'I had it first...' but nothing too bad.
I'm now finding that a lot of the things they want to play with are the same eg. Play doh, play mobil, Lego, craft stuff etc but I keep hearing DD1 telling DD2 'that was MINE before so I should have a go with it first' etc and most of DD2s things were originally DD1s that have been passed along but are still played with by both.
Anyway, thinking about Christmas, I was thinking of giving them quite a few joint presents as it seems silly to give them individual sets of say, play mobil that will be all put together and played with as a whole anyway. I had an older brother and we played with different things so I didn't experience this but did anyone have this issue and did it go down ok or should I give separate things? Seems a bit of a non issue but hey
