At what age does baby outgrow sling? When does baby's fragile spine development become less of an issue?

 

There's not really an age limit for the slings. The fabric has been strength tested at over 80 lbs! I (Leah) could carry my 8 year old daughter in it if I had to. One day my 4 year old hit the end of his rope while we were in the mall. I threw him in the sling, put him on my back, and trucked out of there. I certainly wouldn't want to carry him for an extended period of time, but he hasn't outgrown it!  There are pictures on our facebook page with people carrying toddlers and up. Check it out!  Spine problems have been associated with types of baby carriers where all of the weight is placed at the base of the baby's spine, and their feet are dangling below. I call that type "dead frog carriers" because the baby's just hanging in there without control or support. With a baby sling, the feet are curled up and the baby can push with her legs. She's also more reclined with weight distributed well across her back, just as if you were holding her in your arms.
