The Five S’s

Review of The Happiest Baby on the Block by Dr. Harvey Karp

Author of The Happiest Baby on the Block  and the more recent The Happiest Toddler on the Blockbooks, and DVDs, Dr. Harvey Karp is endorsed by the Surgeon General as well as La Leche League, Lamaze, and the American Academy of Pediatrics (AAP).
Dr. Karp has been teaching his specialized calming techniques for more than 25-years. His methods are extremely simple and absolutely work! His theory is that by creating a comfortable environment similar to the womb will allow a baby to happily sleep more. It does work.
It is easy to follow his Five S’s — swaddling, side, stomach positioning, shushing, swinging, and sucking. Each “S” triggers natural calming reflexes to soothe the baby.
Swaddling is an excellent way to prepare younger children and newborns for a good night’s sleep. Dr. Karp cites a 2002 study done at the Washington University in St. Louis School of Medicine, in Missouri, involving 37 infants (aged 19 days to six-months). The study found that the younger babies went to sleep more quickly after being swaddled. The study also showed that babies who are swaddled, or wrapped tightly in cloth before being put down to sleep, were more likely to sleep on their backs — a position that is now suggested by most pediatricians for prevention of Sudden Infant Death Syndrome (SIDS). “You get the benefit of tummy sleep with the safety of back sleeping,” says Dr. Karp. “It extends an hour to two hours a night the sleep of babies, I like to tell my parents.”
Side and stomach positioning mimic a baby’s posture in the uterus — it also switches off your baby’s Moro (falling) reflex. Dr. Karp suggests placing a swaddled infant on a parent’s lap while seated; put the child on his right side with his head on your knees and his feet on your hip. Then slide your left hand between your knee and his cheek so you support his head in your palm and fingers. Finally, roll him onto your left forearm so his stomach rests on your arm; bring him in close to your body, lightly pressing his back against your chest.
Shushing and white noise can also be a benefit for many babies and toddlers. Reminiscent of the womb, white noise is especially helpful for soothing newborns. You can add this to your routine simply by softly “shhh“-ing to the infant as you help her to sleep; or you can play a white noise recording (see Karp’s website for several examples). The sound works to mask other sounds in your home that may wake up light-sleeping children.
Swinging: Since ancient times, parents have employed swinging to soothe a crying baby. Gentle motion mimics life in the womb for your baby—much like “shhh“-ing—and, as Dr. Karp writes, “[it] turns on ‘motion sensors’ in [your baby’s] ears, which then activate the calming reflex.” Dr. Karp’s swing motion is achieved by beginning in the same lap position as in the side/stomach posture (baby swaddled, and stomach-down in your arms). Just add a gentle rocking back and forth by swaying your legs from left to right, and add a little jiggle by bouncing your knees up and down. Or, you can try an infant swing as well.
Sucking is another age-old soothing technique. In a modern-day twist, Dr. Karp suggests using the pacifier for children who haven’t found a favorite finger or thumb to suck. He prescribes bottle and breast feeding whenever your infant appears hungry (a sure sign is when he turns his head and opens his mouth when you touch his cheek), or employing the use of a pacifier when the infant is merely looking for comfort. But when using a pacifier, Dr. Karp says it is important to know when to stop. “At three-months, phase out pacis and wake them up a bit just before you put them to sleep so they can learn how to self-sleep.”

Dr. Karp also covers strategies for calming fussy or colicky babies. The soothing methods are simple and help babies settle down, a prerequisite for falling, and staying, asleep.

  6. Well dr karps methods from happiest baby on the block worked like a charm last week. I swaddled her, put her in the swing, sucked on the pacifier and slep all morning. But mom told me no pacifier or she will get attached to it/become dependant on it. Boy the baby sure did love it while it lasted though.

  7. The methods in this book work! funny thing is, is that when I was raising my 6 kids, i didn't have this book, but just did what came naturally, and these methods are what came naturally 🙂 Now as a professional nanny, i'd like to apply these methods, but some moms just don't buy into the swaddling, or pacifier.
