I have a nearly 10wk old, and given that your babe is 8 weeks, I don't really think an SSC (Ergo, Beco, etc) would work that well for a back carry. I could be wrong, not having tried it,

: but I've done a lot of back carrying in my Ergo and it's harder when they're smaller.
I asked for advice on TBW on getting a woven wrap or mei tai for back carries for an infant, and the overwhelming response was a wrap. I currently have one woven wrap that I'm using for it and it works very well! A little learning curve, but not too bad - I tried it maybe 3 times before I got it. What I've got is a Vatanai striped wrap, the first woven I've really used. Very light and airy yet supportive. Though I haven't got much to compare to!

There are several carries you can do on your back with a wrap - TBW is really a great resource for info on those!

I just got a BH and haven't tried a back carry with it yet. At first when trying the wrap I thought for sure a Mei Tai would make more sense, but now that I've figured out the wrap, I can't see how I'd do it with a Mei Tai!

Other than back carries I love... well, all of my carriers!

I have a pouch (Mamma's Milk) that I use for quick in and out types of carries, but can wear for quite a while, too. I use the Hug-a-Bub stretchy wrap for longer carries when I want more weight distribution and ease of moving both arms. And now I have the BH which I wore for 2 hours today with no problems, and the woven which I'm still getting used to for back carries. I think they all have their own special use and love them each for different reasons!
