there are so many out there it would be hard to choose. I have heard good things about hotslings if you are looking for a pouch, the other option might be a ring sling which is similar but has a little bit of adjustibility in it if you want to change between you and your partner. Make sure you get something that sits on your shoulder, not across your neck (which is where a lot of the buckle slings sit - not comfortable).

If you want more information about sling and the different types, google "mamatoto" and "the babywearer" to get good sites that are informative.

I actually made my own ring sling. If you can sew, even at a basic level (that's all I can do), look up "sleeping baby" for some really good instructions and how to make different slings
