Why Do Babies Like Pacifiers & Sucking? (2024)

Babies like sucking on pacifiers because it reminds them of being in the womb. In fact, sucking is one of 5 womb sensations (known as the 5 S's) capable of triggering a baby's innate calming reflex.

About a Baby’s Sucking Reflex

Sucking's power to calm babies is quite extraordinary: It lowers the heart rate, blood pressure and stress levels; it even reduces crying after shots and blood tests. It's amazing how much pleasure a simple pacifier can bring your little one throughout the day!

Why Sucking Makes Babies Instantly Happy

A baby's survival depends on sucking. This skill is so important that babies start practicing long before birth! In utero, it's easy for babies to suck their fingers because the womb's soft walls deflect their hands toward their mouth. After birth, newborns don't suck their fingers much because they have poor muscle coordination. They may attempt to suck but they're more likely to whack their hand their nose than find the mouth. That's why babies are so relieved when we pop a pacifier, breast or bottle right into place.

Doctors call infant eating nutritive sucking.

What is Nutritive Sucking?

Nutritive sucking is when a baby is sucking to gain nutrients from milk.

New babies grow so fast they need a milky meal 8 to 12 times a day. Some people say they eat like “little pigs,” but piglets can’t hold a candle to our babies! Every day our little ones “snort down” three ounces of milk for every pound of their body weight. That’s like you guzzling five gallons of whole milk every day, seven days a week!

What is Non Nutritive Sucking?

While nutritive sucking is when a baby gains milk for sustenance, non nutritive sucking is when a baby is sucking but are so full that they are just doing it for comfort.

When babies suck on a pacifier, toy or thumb, it's called non-nutritive sucking (because it yields no nutrition). Like baby meditation, non-nutritive sucking helps babies stay calm amid the chaos of the world around them. But as hunger builds, your baby will eventually spit the pacifier out, as if to complain, “Hey, I ordered milk—not rubber!”

After some great nutritive sucking—that is, a good feeding—she’ll happily accept the binky again.

The Benefits of Pacifiers

Some parents never offer their baby a pacifier because they worry it's habit forming. Fortunately, it's impossible for babies to suck too much. It isn't candy or an addiction; it's an integral part of the 4th trimester and one of your baby's first steps toward self-reliance.
