my dd 13 shares with dd6. Not an ideal situation but there are no alternatives
My dd 9 shares with her 3 yo brother. Again, not ideal as she is beginning to grow up and will likely need some privacy soon, but she is the only one who can sleep through his loudness. That is why he shares with her. She is the soundest sleeper.
Would love to have enough room for eldest to have her own room, as she is in a different phase of life as the others, but this is what we've got. If we had the extra space, eldest would be alone, two middle dd's would share, and boy would have his own place.
If the two littles have to share, would you be able to stagger bedtimes, so they could go to sleep w/out keeping one another awake?
Or sometimes, when one kid got a late nap and was restless, I would let a child go to sleep in my room and daddy would move them later.
