RE: Where to get diaper bag accessories?
You can gte changing pads anywhere (Target, TRU/BRU) for a few $$. You can get one of the hardsided travel wipes containers (liek Huggies or Pampers) at most any Target-like store or drugstore.
The other stuff is kind of useless in my opinion. I use a Ziplock bag for a dirty duds bag. This works great since it can lay on the bottom of the bag and takes up no room, but its there if you need it.
