Curing Colic: The 4th Trimester, the Calming Reflex & the 5 S’s
GE Reflux – “spit up” supreme?
Many crying babies are suspected of having gastro-esophageal reflux disease (GERD). Most babies have reflux of course, but they are fine...we just call it “spitting up.” Some babies do have GERD as a cause of pain but it is not a common symptom.
DeBoissieu and colleagues(9) reviewed 219 infants under the age of 1 month referred for evaluation of GERD. Of all the babies with reflux 44% had malaise, 33% significant emesis and 30% poor weight gain…but none had pain after eating. Findings of inflamed esophagus did not correlate at all with crying.
Heine and associates in Australia reviewed the records of 24 extremely irritable babies under the age of 3 months who underwent testing for reflux…only 1 had GERD (10).
In a very sophisticated study, Moore and colleagues treated 30 irritable infants (3 to 12 months of age) who had proven GERD with the medicine omeprazole. The drug significantly decreased the acid levels in the esophagus…but did not reduce the babies’ fussiness at all.(11)
One of the biggest reasons babies get misdiagnosed is because of a normal baby response called the “gastro-colic reflex.” This is the reflex that makes babies poop right after they eat. For most babies, this reflex happens without them feeling anything, but a few infants totally overreact to it (much the way some babies overreact to loud noises). In the middle of a feeding they may suddenly double up and cry.
Colicky crying usually peaks at 6 weeks and is much better by 3 months. Food allergy and GERD on the other hand are usually still quite bad at 4 months and can take a year or longer to disappear. So, suspect an intestinal problem in fussy babies whose crying does not get better as they pass 3 months of age.
So, if unhappy babies aren’t crying because of upset tummies, what exactly is going on? As odd as it sounds, I think the real reason our babies get colic is because, in a certain respect, they’re born 3 months too soon!
The Missing “4th Trimester”
Baby horses can walk and even run on their very first day of life. They are truly ready to be born when they leave their mother’s womb. By comparison, our newborns are more like fetuses than infants. They have irregular breathing, tremors…and even need help to burp. It is only after 2-3 months that they smile, coo and finally seem ready to be here.
Our babies don’t have big strong bodies, like horses, but we have big brains. In fact, they are so big, at 9 months giving birth is an almost impossible squeeze. A dilated cervix is 10 centimeters in diameter (31.4 cm circumference) while a newborn’s head has a circumference of 34-35 cm. Our big-brained babies have to come out after 9 months gestation, however, in many ways, they could really use a few more months of the stimulation of the uterus.
Yes, I did say stimulation. In the womb, fetuses are constantly massaged by the muscular walls of the uterus, frequently jiggled and 24/7 they are surrounded by the crash of blood whooshing through the placental arteries (a noise that is louder than a vacuum cleaner!).
Most parents around the world intuitively mimic the rocking, holding and shushing of the uterus, but in our culture, we are mistakenly taught to whisper and tiptoe around our babies, believing that they need a quiet and still environment…nothing could be further from the truth! Rather than being over-stimulated, most of our babies are seriously under-stimulated.
Recreating the sensory milieu of the womb is so important for newborns, not because they are nostalgic for the “good life” they had inside, but because it actually triggers an important, but previously unappreciated neonatal reflex, I call the calming reflex.
The Calming Reflex
The calming reflex is a “primitive” reflex (or, group of reflexes) that is almost an automatic off-switch for a baby’s crying. I believe it evolved over the millennia not as a way to calm fussy babies, but as a way to calm fussy…fetuses. During the last months of pregnancy, this inborn response it keeps virtually entrances fetuses, thus lessening the chance they’ll move around too much and accidentally kink the cord or get stuck in a position that would make delivery impossible.
The 5 S’s
Unlike the knee reflex, which has only one way of being triggered, there are 5 things a parent can do to activate their baby’s calming reflex has five - the 5 S’s: 1) Swaddling – tightly, with the arms down, 2) Side/stomach position – while the back is safest for sleeping it is least effective for calming crying, 3) Shushing – loud, continuous white noise, 4) Swinging – rhythmic movement, 5) Sucking - For a very fussy infant, these ancient methods need to be done all at once and as vigorously as she’s crying. (You should feel like you’re “dancing” with the baby, but she’s leading!)
Sound too good to be true? Dr. Steven Shelov, editor-in-chief of the American Academy of Pediatrics’ Caring for Your New Baby and Young Child said about The Happiest Baby DVD, "Dr. Karp's approach is the best way I know to help crying babies."
(Dr. Karp’s approach is discussed in his DVD/book entitled, “The Happiest Baby on the Block: The new way to calm crying and help you baby sleep longer”. For more information visit www.thehappiestbaby.com.)
