Say you have a child in school and an infant. Twice a day you have to get to the bus stop with the smallest child and you walk - it's about 1/4 mile to the bus stop.

What would your preferred method of transportation for the infant be?

Car seat in stroller? Bassinet of some sort? Just carry the baby? Something else?

We already have 3 strollers - a Britax B-Agile , umbrella stroller and Chicco keyfit snap n go (our new to us infant carseat is a Chicco)
