Re: Best carrier for a bad back
After 4 children and just about every sling/carrier later...I have found and absolutely LOVE the Ergo!!! Your babies weight is distributed more onto your hips instead of pulling on shoulders/back. It works from newborn-45lbs!! I did yard work for 3 hrs with my 2.5 yr old in the Ergo and was not at all uncomfortable.
Great carrier...highly recommended!
