This is one of my all time favorite carries. It’s simple to do, easy to tie, secure, and babe can have hands out or hands in if they are younger. It can easily be done from about 3 months. I am comfortable putting babes on my back as young as six weeks, but exercise caution and care with airways and make sure to check breathing often.
Instructions for this carry can be found here. We were at a football game, and the little monkey just passed right out.
Babywearing for the win!
