I'm looking for a pushchair (for older baby/toddler so doesn't need to be a travel system), I would like one that is really lightweight and folds small, doesn't take up much boot space etc. But the streets near my house including the school run route are all uneven slabs and potholes in the concrete, very rough going, and to get on and off my street there is a small flight of big, shallow stairs (so the whole pushchair can fit on one step and the steps are shallow, so it's like going up and down a series of curbs). Is there a stroller on the market that can handle this despite being light and compact? Wondering particularly about the Bugaboo Butterfly which I like the look of but the wheels are so tiny!
