sorry going against the grain here, I bought one for Sam when he was 3 months old, and to this day he has slept in it for a total of 2 hours. He was always a bad sleeper, so we bought the hammock out of sheer frustration, well $350.00 later and no change in sleep it is back in the box, waiting to be sold. I don't know if it is just him or because he was a bit older when we first put him in it but he just hated it. We have since spent $400 on sleep school which worked like a charm.
