Alright, more experienced babywearers, correct me if I'm wrong...
I think you misread the previous info. Snugglis let the babies' legs just dangle, putting all the weight on the crotch/pubic bone. In a back carry w/ mei tais and wraps the legs and butt are both supported in a seated position, thus allowing for proper blood flow and joint movement.
See how your ds sits on the floor? That's a very similar postition to how he will be in a back carry. I really need to practice getting dd on my back w/ my wrap b/c so many mamas say it's the most comfortable....
Good luck!
