Donna, it depends on if you are willing to wrap a very long cloth around you and Cruz (like the last 2 photos I posted) or if you'd like to go more simple and buy a carrier with buckles.
Woven wraps are the long fabrics you would wrap around yourself. Mei Tais have a more structured body with long ties to tie around you, some also come with buckles.
Here are some of my favorite brands: Girasol, Tula, Mei Tai Baby, Infantino, and Maya Wrap.
I really like Mei Tai Baby, because you can build your own wrap by picking from the color and pattern. Since it's custom made, it will take a bit longer to make and ship than the ready to ship ones.
I have a custom made Mei Tai Baby wrap, as well as a Girasol woven wrap.
The wraps usually come with step by step instructions on how to do each carry, personally I like to watch them being done through youtube videos.
