Right now, we're in a one-bedroom, but we're moving into our own house May 1, which will have 3 bedrooms. What I'm going to do there is have a separate bedroom and playroom for DS (18 months). The bedroom closest to ours is quite small, and that's where he'll sleep once he transitions from our bed (whenever that happens
). In there, he will have his bed (we're going to buy him a twin), dresser, and the closet with his clothes. Oh and the diaper shelf thingy and pail.
The playroom is larger, but far away from our room and near the living area, which is why we're not going to make it his bedroom. In there, I'll put up some shelves and hopefully bins/baskets for all the toys. I also plan to get a small table and chairs for art projects and the like and want to paint a chalkboard on the wall. All playtime or educational type things will go on in there.
When he is older and wants more space/privacy, he'll probably move into the bigger room and we'll turn the smaller one into a media/game room or something. And if we have a 2nd child while still in this house, we'll have a couple years of co-sleeping before we have to decide what to do with rooms then
