We have a Diaper Dude crossbody diaper bag and I like it, but it's hard to carry when I have both kids with me at the park or the zoo. I like it more for long trips in the car, etc. I was thinking of some kind of backpack/purse that I could throw my stuff and a few baby essentials into, but I can't find exactly what I am looking for.

Do you have a smaller bag or purse you carry when you don't want your whole diaper bag?
