Thank God that I never needed one, given the age spread of my kids, but for the sanity of people like me please don't get one of those really annoying side by side ones that takes up the whole width of a english pathway or grocery isle. I don't even see them here in the land of 12ft wide sidewalks, so why on earht they exist in england I have no idea! Save the money, carrying child #1 and keep the single stroller. My eldest used ot love sitting on top of the buggie!
