I'm not going to get into the whole CC debate....I just wanted to say that I got a hammock a few weeks ago and my little man has pretty much put himself to sleep nearly every single day and night sleep and he now also sleeps a lot longer. I wrap DS then cuddle for a few minutes untill he is sleepy then I put him down. I think they are fantastic...and you can hire them fairly cheaply, just google "hire for baby", they have lots of outlets.
