DS is 27 months. We have a single umbrella stroller we love and will continue to use.

We need to get a new infant seat (and extra base) and stroller / stroller frame for DS#2.

We've tentatively decided to hold off on buying a double stroller. But we're also a maybe 3 kids family. So with that in mind.

scenario 1: do I buy the chicco keyfit and a universal stroller frame...and stick to our plan of waiting on the double stroller purchase.

Or scenario #2: do I buy the britax infant seat and bagile double stroller now, so that we get the most use out of it?
