We've just replaced our three-wheeler with the strider plus, still only using it as a single till March. I like it, but it is still a big fold, so that might not suit. But it can be reversed as Dr Tal said, and it has the second seat. I think if you want a lightweight, small fold pram, you would probably have to forgo having a toddler seat attachment - it would probably make it too unstable. And most lightweight, small fold prams are also not reversable. As Widdley says, its really hard to find a pram that ticks everything!! That's why I have a big pram (which is the strider now) set up for walking, and then a Maclaren vogue, which is an umbrella stroller, in the car for the shops. I plan on just using that for DD and slinging the new baby when it arrives.
