Quoting The Inconspicuous Raccoon:" I'm curious about these things lol."
Moby's only uncomfortable after baby hits like 15 pounds or so.
Stetchy wraps are GREAT for little tiny newbs but not supportive enough for bigger babies.
I would not recommend a peanut shell for a little baby, they're ok for hip carries after baby is a little bigger, but meh.
I would recommend either a good
ring sling or a woven wrap (unless you only plan to wear baby for not-long term, then go with the moby. Just remember it's not going to be the best thing once baby starts getting bigger (and never use a moby or k'tan on your back. Not safe).
