I am doing research on some strollers, but I think I am pretty set on getting the Bugaboo Cameleon. It seems to be the stroller of choice around here, I'd say about 80% of the strollers I see while out eating/shopping are Bugaboos. Besides that I see a lot of City Minis and Orbits?

I was wondering HOW LONG do they ride in this kind of stroller though? The website says "to toddler" and has a weight limit of 40lbs I think (from what I could find on a review). How old are kids usually when they are 40lbs? And I was wondering if WHICH first stroller I buy makes a difference in how long we'll use it? I mean, is it even feasible to think you would use one stroller from birth to say, 4 years old?

Thanks!
