My head is spinning - I can't decide on a pushchair and this is quite possibly the most important piece of equipment for me. I'm a city mom and do not have a car. I need a stroller that is friendly on bumpy city streets, but also lightweight enough to manage on public transport. Also prefer one that is suitable from birth. What is the solution? I've contemplated the Bugaboo, Quinny Zapp, Mamas & Papas new A3 Pramette, but just can't decide - they all have their plusses and minuses. What have you chosen?
