I used the ergo 360 everyday for dog walks with my first, then got the original when he was about two and used it until relatively recently (he’s four now) so both were a great investment. I started using the 360 at about two months so can’t say how suitable it truly feels for a newborn. I’ve picked up a second hand ring sling and K’tan from Vinted for the first weeks for that reason.
I'm going for the nuna cudl as it's won on Mother & baby awards 😍 found one on vinted for £45!
The nuna cudl is fantastic! I had a very heavy and tall baby and I always felt like the carrier was very supportive. It also has a built in newborn support so no extra pieces needed
If you go to your local sling library you can get advice - it’s difficult to say which is the best because it’s a bit like what cut/style of jeans you like. Slingpages.co.uk has a list and map of sling libraries and you can also get postal hires from some of them to try before you buy!
I got the ergo 360 as it was highly recommended and sturdier than a sling/wrap.
