Needing some advice and suggestions. My partner and I have 4 children who live with us. My 2 bio children are a boy 3 and girl 6. My partners children are a girl 9 and boy 12. We have a 3 bedroom house my partner and I share one room and then we have 2 for the kids. Currently my two kids share a room and his two kids share a room. My kids are with us all the time except for 4 days a month. His kids are here every Thursday after school till Saturday at 5 pm. I think the girls 6 & 9 should share a room and the boys 3 and 12 should share a room. In part because of their genders but also because my two bio kids are here the majority of the time and the other room just sits empty 4-5 nights a weeks. my partner doesn't like this idea because my kids get up much earlier in the mornings than his kids. His kids stay up really late 12-1 am at their moms house. Any ideas or alternative suggestions?
