We've been using our B-Ready either with the second seat or the rider board since DS2 was born 2 years ago. DS1 (who is 5.5) is starting to walk a bit more so I'd like to get a lighter stroller to use for walks in the park, quick trips into the mall, etc. Basically wherever we go that we may need to contain DS2 but where Ds1 will either be walking or bike riding. I don't think I want an umbrella stroller because I want to use it for walking which I don't think an umbrella would work well for that, unless there's a good one out there for that. I was thinking about a B-agile but not sure if that is the best choice. I would like the stroller to be light, smooth ride for walking, and smaller than my B-ready in the back of my SUV (not hard I don't think!). I love my B-Ready, just don't need it as much any more and I need something else. Suggestions?
