We're trying to decide whether to go for DC2, and one of the arguments for having siblings is always that they'll have someone to play with and entertain each other. At the moment our DD is very clingy with us and always wants either me or DH to play with her, all day long, so it would certainly be nice for her to have a sibling as another option.
However, my fear is that we'd have another child, and then they don't get on and don't want to play with each other and we're left with two constantly fighting for our attention!
So, does anyone have DC who really don't play much together at all? There would be at least 4 years between the two, which is another worry as they might not have anything in common.
(I should add that I would never have another child just so I can have a break from DD! It's just one of the points I'm considering)
