Yeah, I got all the accessories to DD's nursery set - including the rocker! I regret getting the hamper because a cloth hamper with a netting interior is so impractical on laundry day. So, it's stored away and I got a regular laundry hamper in a color to match her room.
I also think her rocker is adorable, but I hate to clean it if and when she spills something on it. My mom got my son a wood rocker (that matches the color of his nursery furniture) and that is so much more practical with small kids.
With DS, I got everything but the hamper, rocker, and wall decorations. I made so much for the wall decorations that I didn't need the ones to the nursery set.
And yeah, I've never used the diaper stacker with either nursery. It came in a package set with the comforter, bumper, and such, so I had to get it.
