are the ryco ones thet cheaper version of bjorn? they don't look very secure for little babies - tend to flop around in there - and very narrow crotch, so legs hang down and lots of pressure on the spine and not good for the hips. and they hang off your shoulders, so as your baby gets heavier, it's pretty uncomfortable. bjorns have the same issues, though I think there's a model with a waist strap as well, that might be a bit more comfy? i think the main problem with bjorns are that they're really overpriced for somethign that isn't comfortable to wear for long - in contrast, a manduca, for eg, will adjust to fit from 3.5kg to 18kg (?), front or back, and carries baby/toddler in a more ergonomic position.

well, if she likes the sling and it's comfy for you, then it's probably ok How did you have her in it? cradle?

If you look on the fb page, there are 2nd-hand slings - they're often not all that expensive. There is also a sling library in perth - you pay $20 for a year's membership and and try a range of things. the woman who runs it is very nice & helpful. Not sure if there's an additional fee per carrier you try? It's called carried away if you want to search for it.
