I don't know if it's still available, but there was a time when snugli made a sling-style carrier. You didn't need to figure out how to tie it, it just had an adjustable buckle. It's called the snugli early care sling carrier. You can find them on EBay, no problem. I just looked and found a few.
Babies R Us also carries a product called a sling rider, by Infantino. It is the same idea, if you would prefer to buy new, and costs $30. Again, no figuring out how to tie it on and make sure baby won't fall out, just an adjustable buckle.
Good luck, and congratulations!
