I'm looking for a lightweight buggy suitable for a 1 year old which I can push with a straight back! I'm a mum of 3 whose spent most of the last 7 years stooped over a puchchair or pram! My partner is 6ft 2. I've looked at a Maclaren Techno XT but it seems a bit on the heavy side (I had a Maclaren Volo for my oldest 2). Any suggestions gratefully received!
