RE: Which SKIP HOP bag hould i get?
Congrats! Skip hop makes 3 styles- the duo (you have that one), the expo (same as the duo but the bottom unzips to expand) and the dash (messenger-style). Honestly, I don't think any of them will be much bigger. They all seem to have about the same amount of storage space- the dash has more horizontal space while the duo and expo have more vertical space, but overall the space is about the same IMO (although if you need something just a bit bigger than the duo the expo does expand). It may be time to go up to the next size in a diaper bag. Maybe a timbuk2 messenger bag? Or a land's end do it all?
