Calming a Crying Baby

There's nothing like an inconsolable, crying baby to put a parent on edge. What would it be worth to know a routine that would reliably calm down an infant?
Dr. Harvey Karp, author of The Happiest Baby on the Block, proposes a combination of behaviors that will quickly soothe most babies. There are five activities used to calm the baby he refers to as the "5 S's":

• swaddle
• side/stomach position
• shushing
• swinging
• sucking
