My husband and I are trying to figure out if we need to get a stroller to use right away, or if we can make do with snapping their carseats into a double snap and go (we're having twins). What did you do?

Here's some additional info about our situation:
- The stroller I want (Bumbleride Indie Twin) is suitable from birth, but cannot accommodate snapping two Chicco Keyfits in side by side (that's the carseat we'd like to get).
- We live in a medium-ish sized town and drive everywhere, so they'll obviously be in their carseats a lot (points for the snap and go).
- I'm thinking we'd mostly need a stroller for walks around the neighborhood, grocery shopping, doctor's appointments, etc. Some of these things (walks) it would be nice to have a nice stroller right off the bat and others (grocery shopping) the snap and go would be preferable. (We also plan on trying to each wear one when we're able to go grocery shopping together).
- They are due in May and the weather here is usually perfect by then, so I am hoping to get them out on walks pretty early on.

We will definitely get a stroller eventually, but we just don't know if we should push to get one before they get here or wait until after so we can see how they tolerate their carseats/the snap and go/being worn. Any advice??
