We're both suburban mothers with smaller homes who are always looking for space-saving solutions. Both of my children's rooms had the louvered door style closets (not a fan). I got rid of the doors and used the top of chests of drawers for my changing tables (I also have those furniture lifts/ bed riser things to make it tall enough). With my son, doing this the second time around, I've hit on a couple of ideas that I think are extra winning.
I received about a million of those little, thin receiving/swaddling blankets. Neither of my children have wanted to be swaddled for very long, so that leaves me with unused blankets that I don't feel quite right just getting rid of. I use them as burp cloths (my son is quite the happy spitter) and I layer many of them on top of each other, tucking them in nicely, on the changing pad. That way, when there's a leak, or stain or whatever, I can just strip off the top layer and have a fresh, clean surface.
Hope some of these ideas might be useful to someone else out there!
