I wanted to add to your diaper backpack post...I got a Stephen Joseph backpack that has J's name monogrammed on it at one of my shower's. I started to mention it on the other post but I thought it was too small for what you are wanting. Anyway, I got it out to pack for our trip last night, and I think it's a perfect size for diapers, etc. and has a side zip pocket that a cup would fit in. Plus, A could use it when she gets a little older.
