We are a blended family with another one on the way. At present Miss 6 and Mr 2 have their own rooms, they have shared before at 4yrs and 10months. We are trying to find solutions to sleeping arrangements once baby comes. We only have a 3br house and can't afford anything more. We initially thought we'd have Bub in our room with us for about 1 year but my partner suggested Miss 6 and Mr 2 sharing again. I hadn't really thought about it but was wondering if anyone else has opposite sex siblings sharing rooms? Also, would it be a better idea to have Bub in our room for the projected year and then have him/her share with the same sex sibling from then?
