I have a Baby Bjorn Active from when my 2 yr old ds was born.
I found it to be uncomfortable for baby's hips and legs and won't be using it for my newborn son at all. It was comfortable for my DH and me, but since we don't feel it's good for baby I'll be selling that soon.
We have a solar veil ring sling I bought off eBay from a WAHM when my toddler was a wee babe. It was just ok, since my son hated being worn. It was great as a shade for the stroller on hot sunny days though.
I have no idea where this sling went in the 2 moves we've made since I bought it.
I have a Moby wrap (in Moss color).Moby Wrap Website
I really like this wrap and so does baby. It's great for extended wearing around the house doing chores, or for long trips out. It puts pressure evenly on all the right places on my body and really holds baby securely. It is kind of a pain to put on, and not good for short wearing times. It has a lot of fabric and it can get very hot for us (but not baby).
I have a Kangaroo Korner Adjustable Fleece Pouch (KKAFP) in Saphire Fur fabric. I bought this color for my DH who loves blue and wouldn't want to look feminine while wearing it. It's very pretty though.KKAFP Website
This has been the best carrier for us right now. Once adjusted to the right size, we just slip it over the shoulder, put the baby in, and go. My DS likes the tummy to tummy carry the best for this pouch, though when DH is wearing it, the baby somehow ends up in a sort of cradle carry. He puts him in differently than I do. The pouch stretches perfectly right around the baby and the wearer's shoulder like a well fitted glove. The cons for us have been the baby sometimes overheats if we're in a warmer environment (though the baby stays toasty when in colder environments, so this can be a pro), and as the baby gets bigger I will probably experience pain in my shoulder and neck due to a prior accident. If I wear it too long my lower back starts to hurt a little, but only if it's been hours and hours. Easy to nurse in public discretely (sp?) while wearing it.
I have a Kozy Mei Tei Carrier coming.Kozy Carrier Website
This carrier got the best overall reviews out of all the Mei Tei carriers, especially for younger babies. We ordered it in Windy Day fabric with natural straps. I hope the straps are wide enough for me so I don't experience neck pain (and the headaches that come with it) as baby gets heavier. There weren't too many fabric choices.
Hopefully this is all we plan on getting for carriers. I like practicality.
