Speaking of slings, This website tells you all about wearing your baby and even has instructions for making your own carrier. http://www.mamatoto.org/
I like unpadded ring slings the best because of their ease of use. They can also be worn by people of different sizes. I made a couple of different wrap carriers. They worked great for a newborn, but when my child got bigger I found it harder to tie them tight enough. I’ve never had a mei tai (ABC carrier), but I assume it would be the same. Does anyone else have a favorite carrier?
