It depends what you're looking for. We tried a few from a sling library last time, which are great for getting an idea of what works for you without spending a lot of money first! I really liked a ring sling when baby was very small but found as soon as they're a bit heavier the weight distribution was no good. The stretchy types are lovely comfy material but I hated needing to wrap them all the time, they're soo long they drag on the floor and get dirty! So this time we're going for a close caboo, which is the stretchy material but pre-tied and then we've got a moby aria, which is a more structured carrier for when they're bigger xx
