I have a Baby Bjorn, a Moby Wrap, and a Sleepy Wrap (similar to the Moby but stretchier fabric). I had a lot of problems w/ the Moby - IF you can get the baby into it properly (no gaps, not too tight or loose, baby's nose & mouth visible) it's great. I will try it again when my LO is older and can hold her head up. The Sleepy Wrap is much easier to use but not as readily available as the Moby (order it online). Both of the wraps can be worn by you or your partner, adjust as baby grows, and I think hold babies up to 30 pounds. AFAIK
, the baby must face you, though.
Baby can face in or out w/ Baby Bjorn and I can throw it on and have baby in it in minutes. She seems to like it. There are lots of different styles of Baby Bjorns to choose from. I love putting her in it to go shopping rather than have her sit in her car seat in the cart.
Good luck! I think baby carriers are great!
