Why Do Babies Cry?

If there’s one thing everyone knows about babies, it’s that they cry. Frequently. But why do healthy babies cry? The things that make them fuss (and things that won’t) may surprise you.

“Babies are born three months before they’re really ready for the world,” says Harvey Karp, M.D., Los Angeles-based pediatrician and creator of The Happiest Baby on the Block. “What they need is for us to imitate the experience in the womb, which was very active.”

In his 30 years of practice and study, Karp has found that baby crying occurs because:

  • First and foremost, they’re missing the rhythms of the womb. Babies need constant stimulation and motion such as swinging, walking or jiggling. Skin-to-skin contact is also very soothing.

  • It’s too quiet. The sound of blood flowing in the womb is a loud “whoosh,” so it should be no surprise that babies find white noise (such as the sound from the vacuum cleaner) calming.

  • They’re hungry.

  • They need a diaper change.

  • They’re simply uncomfortable. “To put a baby in a quiet room by itself on a flat bed may be something you or I would like, but for a baby, it’s sensory deprivation,” says Karp.

And then there are some persistent myths to debunk. As Karp explains baby crying does not occur because:

  • They have gas pains. Gas is one of the first things parents blame when babies are tearful, but Karp insists it’s a highly unlikely cause of severe crying.

  • They’re overstimulated by the world. This is an old wives’ tale, says Karp. When you remember that babies are surrounded by noisy, pulsating sounds inside the womb, you realize that it’s just as likely — if not more likely — for a baby to feel upset by an under-stimulating environment.

  • They sense their mother’s anxiety. Babies aren’t yet able to tell when their mothers are worried, explains Karp.

You can cope with a baby that's crying by using Karp’s Happiest Baby techniques, which he calls “the five S’s”:

  • Swaddling. Wrapping a baby’s arms and body securely with a blanket mimics the snug and comforting confines of the womb.

  • Side positioning. Hold baby in your arms on its side, slightly forward-leaning. Stomach positioning (aka tummy time) is also good, but never put newborns and very young babies to sleep face-down.

  • Shushing. Make a somewhat loud “shushing” sound near your baby’s ear, or play a CD of white noise.

  • Swinging. Use a motorized infant swing when you need a break. Ones that recline and come with a secure harness are best.

  • Sucking. Give your baby a breast, a bottle or a pacifier. Sucking on something is a great distraction!

These techniques flip on your baby’s calming reflex. Start with one S and add more as needed until your crying baby is soothed.

    Mostly the babies cry due to tummy troubles if they are gaining weight. The best way to cope with fussiness out of colic, constipation, reflux or any other tummy ache, is babies magic tea. It worked for my both babies during their early childhood.

    My now 17 month old son would only sleep on his belly. He would fall asleep on my shoulder or if I lay down on my chest. As soon as he was on his back he would wake up & acream, So 1 night I put him on his belly he slept for 7 hours. He was 2 1/2 months old. I told his Dr. who answered I am suposed to discourage you from doing that but if it is the only way he will sleep wiyjout being held then do what you have to do. Just keep the moniter turned up & check on him before you lay down.

    I think that the fact this article says over stimulation by the world is an old wives’ tale is very interesting.
