We have a 4 bedroom house.
Girls share 1 room together (since Charlie was born), in 2 twin beds. They LOVE it.
Charlie is in the nursery which is smaller.
The 4th bedroom is another tv room/computer room/more toys room/and treadmill room w/a futon in it so that's where guests can sleep too. It's HUGE & over the garage w/a teeny closet that would NOT make a good real bedroom...it's more like a nice huge bonus room.
In our next house (whenever & wherever that may be!!) We will get 5 bedrooms PLUS a basement & the girls will get their own rooms & share a bath. Charlie will get his own room & own bath.
