Babywearing is a skill to be learned, and not a product you can buy in a box. I promise it will be hard and confusing at first, but after a few tries both you and baby will become very comfortable slinging.
A very few rules of thumb: Keep baby’s face visible, and within kissing distance. Keep baby’s knees higher than her bottom, in a deep squatting/clinging pose–her natural posture. Listen for clear breathing, no snoring or grunting. Wear baby on your chest/sternum, not low on your belly or pelvis. Straps should be spread wide and very snug for greatest comfort.
Seek out other babywearers, your local babywearing group or a babywearing group online for support and wisdom. Remember parents have been slinging for centuries: everyone can do it, you just need to figure out how!
