With my first baby, I carried him in a sling most days as we were out exploring in London, jumping on the Tube and around galleries and museums and everything was easier without a buggy. With my second, I used a sling the whole time because it made it so much easier to run around after his big (toddler) brother at the same time. And with my third, a sling is the only way to have two spare hands to hold onto my sons whilst looking after my baby daughter too. So I've been sling-sporting (or baby-wearing as the gurus put it) for about six years, mostly using a BabyBjorn.
It was fine when the babes were tiny and in the classic model. But then as they grew I needed more back and shoulder support so moved on to the Air model. And that's when it went wrong. I'm small - still wear kids' trainers, have been known to buy clothes in age 12 in Zara, am around 5"1 - and so many slings I tried just didn't get tight enough on their shoulder or back straps.
