Scoobiesmomma, I choose the same diaper bags as you... wonder if it's a Bal thing. Haha! I bought a Storksak when I had my first. Didn't end up using it much because I couldn't hang it behind the stroller. Anyway, now that I have a second one on the way, I'm planning to get Skip Hop Double Duo because both of them will still be in diapers by the time Baby #2 arrives.
For trips, I used a big Longchamp Bag.
