I had two slings from Mamma's Milk (
http://www.mammasmilk.com/ ) -- the patterns were darling, but James, as a newborn, didn't warm up to them. I guess he felt squished or something. And when he was big enough to support his neck, I wore him on my hip and it amused him while I gave him a tour around the house. They did not really get much use because I didn't go on trips or places that would require carrying him a long time. Loading him in and out of the sling was more trouble than just standing in line at Starbucks for two minutes, getting my coffee, and getting back in the car. I was fine with just holding him normally then. I also confess that part of it was that I never felt like I got the hang of using those type of carriers, how high it had to be on my shoulder, exactly where he was supposed to be resting, was I cutting off the blood circulation in his legs, etc? We also had a front loading Bjorn and he loved that. He liked facing forward and looking around, but there was a weight limit on it, which he reached pretty quickly. (He's a eight month old and I'm already putting 12 to 18 month clothes on him out of exasperation on how tight
some of the 12 month clothes have become.)
I do have a camping trip coming up in May and the question is ... will he be walking before then and not want to be carried or can I pack those slings and give them one last try? I am saving the slings for the next kid because every kid is different.
Also, here's a fun place to check out if you're not aware of it:
http://www.thebabywearer.com/ Lots of different products, people love different things, and it really appealed to the artist in me that you could pretty much request certain patterns/styles just for you depending on who you were ordering from. I never used this board for anything other than looking at pictures of various baby wearing items and reading feedback about how people were using them.
Oh, the mamma's milk link also has several doll drag and drops you can use. If you buy one of their slings, then you get access to the same avatars, but with their custom slings added. This were mine (left was the custom avatar, right is freely available):
