We are currently in a 3 bedroom house. The master bedroom is downstairs and the other two bedrooms are upstairs (LO's room and currently a guest room).

If & when we have another, DH and I are discussing whether to turn it into a nursery and lose the guest room, or to have LO2 sleep in our room for a while and then have the LOs share a room. I doubt I will want to be going up and down the stairs to feed a newborn and if I have a RCS I will not able to do the stairs for the first weeks anyway.

If your LOs share a room, when did the second LO move in? How did you change the room? Do they also share a dresser & a closet? Was sleep disrupted for either child?
