Let's discuss which brands/types whatever of baby carriers you are going to use. There are so many different options out there and I'd like to hear what worked well for others/what people are going to go with the first time. So let's hear pros and cons.
Ergo: I liked it. Durable, ok comfy wise, but did start to hurt my back after awhile. I never mastered the back carry position. I had the infant insert and used it when DS was little, but friends have told me they just as easily rolled up a blanket to support the little one. I didn't use it inside; it felt like a backpack to me and so I only used it for walks and things like that. Recommend.
K'tan: I read in a review to order a size smaller because the material stretches. Uh, I ordered an XS and there was no way my post partum body and my 95% er newborn were going to fit into it. Never used it and do not recommend. Maybe if it fit I would.

Re: baby carriers

<p align="center"I had a cousin who wore all her kids and really likes the Maya wrap, I mean to the point she wore her first one and I don't think anyone else held him.
I also have a Boba 3G. I used this more starting around 4-5 months and have been using it ever since. The stirrups are great now that my DS is bigger. We've gotten quite a lot of use out of it. I wore him on the front for a long time, but eventually he got tall enough that it was hard to see around his head. Wearing him on my back has been great for hiking and doing house chores with a fussy baby.
I also have a ring sling that I got from Sleeping Baby Productions. I didn't have it until my son was 4.5 month old so I'm excited to try it out with a little one. I think it will be very convenient especially for using out of the house and I think it will be easy to nurse in.

SNUGLI: I hated it. My baby's legs went straight, not cuddling me. And it hurt my shoulders.
Baby wearing newborns is essential IMO. And beyond. The ergo is my favourite for when they outgrow the moby. Fast and easy. Durable. Comfortable.
Moby - Loved from 0-4 months and saved my life
Beco Gemini - Loved. Supportive, comfortable, easy to use. But he outgrew around 9/10 months
Ergo - Didn't work for me, I found it uncomfortable
Lillebaby Complete - Bought when he outgrew the Beco. I adore this carrier and can still comfortably carry him at 21 months. It's pretty much the best features of the Beco and Ergo combined. It also had a lumbar support pad which makes a huge difference.
I will be getting a Ring Sling for this babe and a Tula Toddler. We are trying to get by without a double so I figure there will be times when babe needs to be worn and time when the toddler needs to be worn.

<p align="center"The K'tan - I tried the summer version (breeze, maybe?) and couldn't get a good fit. I exchanged it for a fabric one and liked it, but I only used it a handful of times with DD because she was born in July in Texas and it was just too warm for me. She tended to cry in it, but I think I just didn't use it enough to where she was comfortable. I'm hoping to use it more with this LO, especially since we'll be running around after my DD.
Moby - I have a borrowed Moby and never used it, partially because of the Texas heat in July. It wasn't hard to use, particularly, but the other carriers I had were so much easier (and less fabric), that it would have been my last choice.
Ring sling - my DD loved being in a ring sling, but I didn't put her in one until she could hold her head up. She would nap in it in the front carry position facing me. I mostly used it around the house when I needed to get some work done (I work from home and had DD home with me until she was 7 months old). I wouldn't have used it with a newborn, and it never felt as secure as the K'tan or the Ergo, but I liked it.
Ergo - I tried the newborn insert, but my DD hated it and didn't really come around on the Ergo until she was about 8 months old. That said, I still use it on occasion and love it now. I flew with my DD a few weeks ago solo, and I don't know what I would have done without it! It does feel like a backpack, though.
I ordered a Beco Gemini and loved it, but it was expensive, and since my DD didn't instantly love it, I returned it. I may get one this time - we'll see.
I love both the ergo and tula. I hated the moby wrap, it was super hot for me even in March in MN. I hope to find a sling of some kind for new baby.

Had a Bjorn but all the weight hangs from your shoulders so it's not ergonomic after the early infant phase. Plus baby's hips are not supported. I wouldn't recommend.

Also, moby's are really only good up to 15lbs and no back carris because they are a stretchy wrap.
Bought an ergo when B was 9 months old. It was definitely more comfy as he got heavier. DH prob used this one more than the K'tan... back-carrying in super-convenient.
Since you have time, Ergos tend to hit the sales sites periodically (Zulily, Gilt, etc). Also the Gray Galaxy ones are all on sale at Targets right now since they are discontinuing that print. Your odds of getting an Ergo at less than retail are pretty good if you wait for the right time!
Unfortunately the same can't be said for Tulas. They sell used for almost the same price new!
As for knock-off Ergos, I heard the problem with those is that they are not safety tested like real brands are, so people have issues with like, buckles breaking, stitching ripping, etc.
In the original I boughta size smaller due to stretch. With the breeze I ordered my normal size that's recommended.
I still use my ktan and it's my husband's favorite too.
Maya wrap (ring sling) is my favorite for him being older *1 year* because I carry him on my hip so it's comfortable.
Ergo is alright. I hate it for the nb stage. In fact, we've never worn it out of the house.
I bought it for Dh, but he'd rather have the ktan.
The ergo will be better for older kids IMHO.
I still feel my lo is so little for it. He's only 17 lbs though. Maybe I'll try back carry with it.
