I am considering the uppababy or the bugaboo bee plus. I live outside London, and sometimes go in, but mainly drive locally so my pushchair needs to be suitable for both public transport and getting in and ouut of the car. One of the things I dislike about the bee is the newborn seat, as my baby will be little during the winter months so I prefer the uppababy for the carrycot. But is the uppababy really heavy and big to lift?
