Day 35 - Ritualistic Chillins

Supposedly, kids like having a bedtime ritual. It helps get them into sleep mode at night, so that they sack right out. I've yet to hear what portions of the ritual elicit which effects though. If the bath helps them close their eyes, and the swaddle helps them tune out the world, what keeps them sleeping past the four hour mark? Is it a certain combination, or order of operations that's required? Should she get rocked exactly 32 times before being put down? Hmm... Perhaps OCD has its uses.
