I had the same issue and got the ergobaby omni breeze which is great for my back
Sleepy Nico is a good lightweight one but might be worth asking in the Baby Wearing UK Facebook group for recommendations or visiting a sling library if you have one nearby for someone to let you try some on x
I’d also recommend consulting with a babywearing consultant and/or sling library as every body is different as is the best fitting/feeling sling for each.
i love our tula explore xx
Mamaruga Zensling - but recommend going to a sling library to try a few! We had a baby Bjorn before too it’s amazing how different carriers suit different people so best to try before you buy!
We also had the baby bjorn minj and just got an ergobaby omni 360 as it was hurting back now she’s bigger. It’s so great as takes all the weight through your hips and we got off Vinted for about £50 rather than £170 new and just ran through the washing machine with anti bac and detergent
