My mother says that I was very suspicious of any attempt get me to go to sleep when I was little. Quiet games and lullabies sent me into screeming fits. But if she sang a loud playful song (Pop goes the weasel--my fav.) especially if it included swats on the bottom and bounces, then I'd fall right to sleep.

DS was similar. Skin to skin was not enough and he thought nursing was play time. But a walk around and around the house while we chatted with him about our day, that would do the trick.
