Pavlov’s baby

I think I have accidentally classically conditioned my daughter. From birth to get her to settle down I have sung her “deeper than the holler” by Randy Travis in the most soothing voice a dad can muster. To this day in the tantrums of toddlerhood I can sing that to her and she settles right on down.

I know we aren’t the only ones that have something special like that. What other special ways do y’all settle your kids down?
