Blimey ladies, we have been budy, i can see this being a long post just so i mention everything!
santa - glad you haven't been put off of breatfeeding totally. ok slings, (be warned i could talk about this for hours and gave wirtten many articles so if anyone wants to read them, let me no [big headed emotion])
pouches - not adjustable, so not great for parents that want to share the wearing, often made quite large so dont fit properly. very comfortable, big shoulder pads and very easy to breastfeed in. can wear baby on hip when older, but not for long as weight only spread over one shoulder.
ring sling - a perfect one to start off with. fully adjustable (my rather large df can wear it fine) come with or without a lightly padded shoulder. some have handy pockets on the tail to, so there's no need for a bag. versatile as they get older sk i use mine all the time for quick trips, popping in and out of places, its great for shopping to. it's permanently in the car. takes a little while to learn how to adjust and secure, but well worth it.
stretchy wrap - really good for newborns, versatile to the extreme, many different holds from learning just one way of tying. you just have to learn how to tie it, which is really simple and how to deal with so much fabric. not all that great as they get to about 7/8months as they are quite heavy and i've found that as the material is stretchy it gives quite a bit. however, really nice and cosy for the first 6 months.
woven wraps - like the stretchy but with no give in the material. i fond the material isn't as soft as stretchy, but still comfortable for a LO. Better than a stretchy if you want to be able to put them on your back if going for a long hike. stetchys can go on the back but wovens feel more secure IMO
mei tai can be used from birth if used correctly. really simple - just a square of fabric with 4 straps coming from it, 2 go round your waits and the top 2 tie around you and the baby. spreads the weight evenly around the body (my 35lber hardly feels like he's there) can be worn front, back and hip. personally i prefer it when they're older (9months+)
there are always Podeagis which are korean, like the MT but with just 2 straps, the Hmong, which is also very similar and many more. Sorry this really is long and i haven't even finished yet
