We might be moving to a first floor flat which has its own front door but the hallway is only big enough to actually open the door before you go upstairs. It's not ideal as it doesn't give me enough space to load up pram with baby before heading out into the elements (due Jan '15). So I'm thinking of getting a pushchair which will fold up easily, and have seen the M&P Armadillo and the Baby Jogger City Mini. Are these my only two options? Grateful for advice, or indeed advice on how to juggle things up and down stairs...!
