I absolutely adore our Bushbaby Cocoon. We bought the Cocoon for our second child, after struggling with a competitor's sling with our first child. We found it easy to use from Day 1 - getting our baby in and out of the sling proved to be an absolute breeze, and as the part of the harness that holds the baby comes away from the sling, it was very easy to lay our son down when he was asleep.
The carrier also proved to be ergonomically suited to us, we're both 6' so can be prone to backache - this was not a problem with the Cocoon.
The fabric of the Cocoon is very strong, and the construction is robust. We have machine washed our Cocoon multiple times and it still looks like new. We also like the fact that the carrier has clips for ease of use - personally I'm not keen on the 'wrap style' slings as I think that they would take me too long to get the baby into when I need to leave the house in a hurry.
I would absolutely recommend this carrier to a new parent.
With a couple of clips baby can be disconnected from the adult harness so sleep time wont be disturbed!
