Clothes dryer as changing table
Amy's dual-floor diaper-changing solution:
We have a two-story house, and her changing table has always been upstairs in her bedroom (I figured that if I went upstairs for every change, I was getting much-needed exercise, a little at a time). Well, I got pregnant again when she was 10 months old, and over the past few months it has become harder and harder to do the stairs 6 times a day. So, I took a changing pad with raised sides that we had (it's kind of a shallow U shape, if that makes sense, so that the baby can't fall off the table). I put it on top of the dryer on the main floor of our house, and PRESTO! Instant changing station without more furniture (or, God forbid, having a changing table in the living room!!). I figured there were more than a few space-limited families out there who may not have thought of this one yet.
We just kept a little waterproof pad and basket of diapers/wipes/cream on the main floor, then just changed the baby on the floor. Amy's solution is easier on the back, though, and it's nice to be right there next to the laundry.
