When dd2 was a baby it was great, even though it was 3 under 3.

However - ds and dd1 had always been the best of friends until dd2 started getting older and now ds rarely plays with the older two girls, they just fight.

Dd1 and dd2 play a lot together. Except if we have a friend over, then they usually shut dd2 out of her room.

So in my case, it changed everything and put ds on the outer so to speak, but - and this is a huge BUT - he is the only boy and at that age where he wants to play on the wii and not play with dolls. So it probably would have happened anyway.
