I'm a ftm and feeling overwhelmed by all of the stroller and car seat choices! My current plan is to use a graco car seat with the sng for the first month or two, and then transition to just the B-Agile. I was looking at the travel system, but don't want to be limited to only the Britax car seats, and thought the snap n go would be more convenient in the beginning. Does this sound like a good plan? Can I also use the B-Agile from birth for longer walks? Since I'm due this spring, I thought it would be good to have that option as well. Thanks!
