With our nanny share we'll be needing a lightweight easy to use side by side stroller. We have an UBV with a rumble seat for our kids, but both babies are too small to go into the rumble seat, so we need something that will be good for our 5 month old and her 4 month old. I'm looking at the City Mini and different Maclarens (looking at used ones on Craigslist) and I'm wondering what the differences would be. Anyone love their lightweight double stroller?
