There is no question that a baby's cry can cause a high level of discomfort and stress for the listener. Consider the fact that the United States military reportedly used the sound of screaming infants—played over speakers—to train the Navy’s elite SEALs to endure psychological torture! Every year, roughly 15% of newborns are born with colic—a condition that is diagnosed when a baby cries for more than 3 hours per day. All things considered, it is hard to believe that more parents of colicky newborns are not institutionalised each year. Parents and healthcare providers have remained flummoxed by the question of colic—its causes and cures—for ages.
Colic is when a healthy baby cries or fusses for prolonged periods of time (more than 3 hours per day). Colic is generally at its worst between 4 and6 weeks of age.
Colic typically starts a few weeks after birth, and hits it worst at 4 to6 weeks of age.
For most babies, colic can last up to three months, but in some cases up to 9 months of age.
For thousands of years, we thought that colic was an intestinal discomfort that babies had, either caused from overeating or having stomach gas. They would double-up and seem to squirm in pain and often pass gas. In fact, the word colic comes from the same basic word as the word colon. Children would be treated with all sorts of things, from extra burping to hot water bottles for the stomach to special formulas. Studies have shown that, in western cultures, most babies cry and fuss for about an hour or an hour-and-a-half per day, but at least 15% will cry and fuss for more than three hours, which is the medical definition of colic. You will notice it does not say anything about the cause of the crying.
Common symptoms of colic in babies include:
I believe the key to understanding colic is that our babies are born three months before they are really ready for the world. And because of that, they have this funny combination of being over-stimulated, on the one hand, and terribly under-stimulated, on the other (the latter being the much bigger problem). In the womb, the baby has a non-stop symphony of sensations. He or she is being held, touched, and jiggled, and hears the non-stop sound of the blood flow, which is louder than hoovering, 24/7. So to bring a baby into your house and put them in a dark, quiet room by themselves is actually sensory deprivation. Some kids can tolerate that, and some kids just fall apart without the stimulation that they had inside the womb. And, what I observe in my work is that when you imitate the sensations of the womb, it does not just reassure them—it literally flips a switch. It turns on a calming reflex that all babies have at birth.
There are five unique steps that parents can do to imitate the womb and turn on the calming reflex, I call them the “Five S’s”.
Everyone pictures having the perfect baby who is going to be cuddly and sweet and never have any problems. So it is very unnerving to have a baby who cries and cries for long periods, and nothing makes you feel worse than not meeting your baby’s needs. It is even more serious than that, because it turns out that crying and exhaustion are the number one triggers for some serious problems like marital stress, postpartum depression, shaken-baby syndrome, breastfeeding failure, and even infant cot death and suffocation, because babies cry so much that the parent will bring the baby into bed with them and accidentally get the baby in an unsafe position. It also leads to parents starting smoking again, and to obesity (because exhaustion unbalances your metabolism—making you crave sweets and fats—and it also undermines your will power). Besides making you feel incompetent, having a colicky baby actually leads to a whole host of serious and expensive medical issues. Now, colic usually peaks at about six to eight weeks of age, and usually by three to four months of age it is pretty much passed on its own. But if you can do those 5 S's during those first few months, you really can help your baby settle faster. Interestingly, the more you do the 5 S's, the faster your baby will respond to them. Babies learn that those things are going to calm them down.
There are many things that we can do to imitate what people do in Africa, and even to be better and more effective than the mums in Africa. Holding your baby, ensuring skin to skin contact, carrying your baby in a safe sling, and nursing—those are all wonderful ways of meeting your baby's need for contact and for nurturing stimulation. In addition to that, we have got things like white-noise MP3s and CDs, swaddling blankets, and flat swings that can make the baby feel like he or she is in your arms when you have to leave to take a shower or cook dinner. And of course there are dummies for when you are not going to be available to give the boob. So there are a lot of tools that we have to allow us to be effective caregivers.

It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
