Hi there, I'm expecting my 2nd child due on Xmas day. My son will be just over 10 months old. I don't have a car & so tend to walk everywhere with my son. ( stupid I know but it's a conscious choice. I know if I had a car I'd be terrible!) My son is a tall baby, in 12m clothing now so I need something sturdy but not too heavy. Does anyone have any recommendations please? Thanks so much!
