Gemma, eight weeks old today, is still happiest when I am wearing her. My favorite carrier, and hers, is the Moby-type wrap. I find it very comfortable and can wear it for hours without any pain, but it is not easy to get in and out of. The other carrier I have is this sling I made from these instructions. It's made from cotton with 3% Lycra,so it stretches a bit and "hugs" my shoulder. I just can't wear it as long as the wrap.
