Hello, i live in London (pretty centrally) and am about to have my first baby. We don't have a car and live near a tube with no lift. I am looking for an every day pushchair and the two i'm debating between really are the Joolz Aer Plus and Nuna Triv Next. I guess what i'm wondering is how much do people end up folding and carrying pushchairs around London or do realistically the baskets get filled with bumph so you need someone to help carry up the stairs anyway? Joolz Aer Plus is quite a bit lighter and easier to swing over the shoulder which sounds like it could be a big plus but it doesn't have the same features as the nuna triv next (extendable handle - useful for my husband, reversible seat, bigger basket, easier lie flat options etc). I'd love any opinions on either pushchair views on actually what it's like travelling around London with a baby? Thanks!
