Currently living in a 2 bedroom flat with Dp, Dd 5 and Ds 9months. We will be moving to a 3 bedroom house in the next few weeks as 18 weeks pregnant with 3rd Dc and desperately need more space. There are 2 double bedrooms, and a box room that will fit a single bed and not much more. We have decided not to find out the sex of the baby. I had thought if baby was a boy then they both boys share the big room and Dd has the small box room and if baby is a girl then both girls share the big room. But now I'm questioning it and thinking, should Dd have the small box room even if the baby is a girl as she will be 6 by the time the baby is born? We cannot afford a 4 bedroom house at the moment so will be staying in this house for the foreseeable future and I'm thinking Dd will want her privacy in the next few years and may not want to share. Is it best to have the two dc who are the same sex sharing regardless off age gap or should the two youngest share even if they are the opposite sex, since there will be only 14 months between them?
