I've got DD2 due very soon and DD1 will be about 18mths older. I've got one brother but a few friends with sisters and they are mostly really close/best friends. I'm not super close to my brother (love each other, do anything for each other but not friends iyswim) so I'd love some tips on raising siblings who enjoy each others company, don't resent each other, can play, support each other through teenage years and so on.
Obviously there's no guarantees but I feel clueless and it's on my mind more and more as DD2 due date gets closer!
