Hi I've just moved into a block of flats with no lift! I'm looking for an easy lightweight stroller that isn't going to be impossible to get down the stairs each time we want to leave the flat! I've currently got the silver cross wayfarer and it's a night mare for getting down steps and even getting up curbs, I find myself having to put all of my body weight on it and I'm not tiny! So can anyone recommend a lightweight stroller which is easy to get about? Thankyou :)
