I have a 4 yr old dd, 2 yr old ds and baby dd. Currently, two older kids share a room and we have a toy room and baby is in with parentals. Trying to decide for future (12-24 months ish) what to do in relation to kids bedrooms.

Option 1 - 3 kids beds in one room, keep toy/study room

Option 2 - 2 girls in one room (4 year age gap), and boy in solo room

Option 3 - one boy and one girl in one room (2 year age gap), with one of girls in their own room.

DD1 will probably be starting school in 2015.

If you have 3 or more kids, and middle child is opposite gender did you keep same genders together or similar ages?
