I didnt even know there was a hammock thread here! We got an Amby for DS to see if it would help him with his wind and possibly sleep for longer, but he doesn't like it! Well, he likes it if you stand there and bounce him to sleep, and then continue bouncing. If you stop he wakes.
He hasn't been in it for probably a month or two now. Last week he was in a rocker at my parents and worked out if he kicked his legs, then he bounced. I was wondering if he might do better in the hammock now? Will have to try him out in it again and see what happens.
