MacMomo, I'm the proud owner of 5 slings, so if you want to run your choices past me, I'd be happy to help.
I found that stretchy jersey ones were ideal with newborns and loved the Kari-me. It was a bit faffy to tie, but great once it was on, and you can take the baby on and off without redoing it. It is great for cradle carry when very little and for forward and inward facing upright position when a bit older. It is also nice and warm in the winter.
The tricotti is a quick version of the above, two jersey panels where you can do upright or cradle carry. Very practical and quick.
The babba sling (peanut shell type sling) is great for hip carry, when they are bigger, although some ladies quite like to use it from birth for cradle carry. It is fine, but not as snuggly as a wrap around jersey sling IMO.
The baby bjorn was favoured by DP (I guess it probably looks a bit more manly, as it is backpack style), but unlike with the wrap around slings, it is not recommended that you carry the baby for long periods, as it places quite a bit of stress on the babies hips. It can only do front upright carry.
The Ergo is pricey but a wonderful back pack style sling. I did not use it from birth, but you can buy it with a newborn pillow type thing. I used this a lot from 6 months onwards, to do both forward and back carry.
I'm such a sling bore, so apologies to ladies not interested in the subject. Don't get me started on the slings I covet and don't own!
