2 Month Old Baby Chewing On Nothing – What’s Going On?

My little one started to move his mouth in a chewing motion lately. At first, it looked adorable, but then I started to suspect whether it is just a reflex occurring in his developmental stage or something serious? Is that an indication of early teething? It might look like they are chewing on nothing, but your baby could be gumming on his tongue.

Sucking and chewing on the tongue is a natural instinct in babies that comes with breastfeeding; without these reflexes, the baby may not latch properly on the breast to suck milk. The tongue chewing and sucking trigger the release of chemicals like serotonin and dopamine, helping the baby relax and self-soothe.

You may think this behavior odd, but it’s quite common in most babies. This behavior usually starts between 4 to 6 months, whereas in most cases, it may start way earlier, at 2 months.

This reflex usually subsides within weeks, but few babies continue until late adolescence, like sucking a thumb or sleeping with a stuffed toy beside at night.

Newborn to 3 months old

3-month-old baby is actively chewing on his feet, and also nothing sometimes.

The chewing motion in newborns to 3 months of age is in response to suckling action. It’s very strong in the first three months of life, and they will suck on almost anything that comes close to their mouth; newborns usually suck on their tongues.

Aggravated by unconditioned reflex

With a strong suckling reflex, babies must satisfy their urge to suck by latching or sucking on anything.

Older babies chew on their hands or feet, whereas newborns chew on their tongues.

Hunger cue

If your baby is chewing on the tongue or lip-smacking, it could be a sign of hunger. Monitor the feeding time of your baby.

Usually, babies stick their tongue out when they are hungry, but some babies may start a chewing motion noticed that my baby performed chewing action close to feeding time.

This was in response to a suckling reflex and a sign of hunger cue. In infants, chewing or sucking randomly may indicate an irregular feeding pattern.

4 months to 6 months old

Chewing action is most prominent in this age group. Babies start to get to know about their body parts and find something to play with.

Exploring their mouth

Babies are a cute little bundle of joy; they light up our lives with their cute actions coupled with a mischievous smile. But babies are weird too.

They start to explore their tiny tongue, hands, fingers, and feet in their early developmental stages. With their desire to latch on anything that comes near them coupled with suckling reflex, it may seem like they are chewing baby gum.

Your baby could be doing this while sleeping, and it may look like your baby is biting or chewing his tongue. 

Your baby is ready for solid foods

Babies have strong innate reflexes; one of the most prominent reflexes is the tongue-thrust reflex. It is a protective mechanism to forestall the baby from choking any hard thing when it enters the mouth.

This reflex usually subsides within 4 to 6 months, and the baby starts to maneuver the tongue around within the mouth and suck on things. At this age, swallowing motion is more mature and precise. It’s a sign that your baby is ready for solid food.

Sign of early teething

In some babies, teething might start as early as 6 months. You’ll notice a sharp tooth cutting through soar gums, and this period is quite uncomfortable for your baby.

Your baby may discover chewing motion in response to subside the pain. You can rectify this discomfort by putting a pacifier in your baby’s mouth.

Set up a schedule of every 2 hrs, which will help to scale back or eliminate the chewing action.
