The doctor gives very simple advice, demonstrating his techniques on babies in his office.
"I take his right and put it across his body. Then I put his left arm across the body like that.
"I hold it, grab his little bottom and very gently rock them up and down at a 45 degree angle.
"You can see he comforts pretty quickly really.
"I shake his little booty like that.
"Everything you do is very gentle. You don't want to do jerky motions, ever.
"You can see I'm rolling my finger around my chin and look at him. This is a content little baby."
