I'm looking for a good double buggy I can use on hills in the city when I walk the dog, and possibly for a little bit of off road. There will be a 22 month gap between baby 1 and 2. I was looking at the P & T navigator just because of the autostop, but now considering Baby Jogger either the City Mini GT double or the City Select. I have the MB Swift for baby 1, and not completely happy with the foot brake so reluctant to get another MB. Any suggestions or previous experience that could help inform my decision making would be greatly appreciated.
