I bought a sakura bloom ring sling for my bub. Sure she's still only tiny, but so far it's been very kind on my back. I have a lower back injury and since the birth my upper back has been giving me grief but when she's in the sling, my back isn't being aggravated at all. It's also very easy to feed her in the sling and very discreet. DF didn't even realise I was feeding her until he stood behind me and looked down. I honestly think its the best purchase I made.
