i think i am just going to splurge and buy a mei tei for carrying baby on back. she loves the moby as do i, but for the front carrys. would love to strap her on back once in a while and can't seem to feel safe and comfy with it tied on back. anyhow, i went through the reviews and i think the kozy and babyhawk stood out. can you all give any good and/or bad opinions on either??? which is comfier? sturdier?
