Last Updated: 26 January 2021

A baby sucking bottom lip is not an uncommon sight and neither is it something alarming. Babies always look for something to chew or suck on.

However, several new parents have shown concerns regarding their baby biting lip. Let us begin by putting new parents at rest – it is nothing to be concerned about. But a baby chewing tongue or lip could be indications of certain things that as a parent you must understand.

So it’s up to you to pay attention and understand these signs.

And in this article, we shall talk about this habit and what could it indicate. We will also give you a heads up on when to be concerned. Solve your parenting doubt right now!

Signs a Baby is Sucking Bottom Lip

Signs a Baby is Sucking Bottom Lip

A baby generally does it when it is being fed or wants to be fed but if that becomes a consistent habit, you will notice some tell-tale signs. Those are:

Bruise on the bottom lip

In case you notice an unexplainable bruise on and around the lower lip of your baby, there is a high chance that your baby is chewing on bottom lip more frequently than babies generally do. If you see red marks turning into purple, that too could be for a similar reason. Watch out for such marks.

Chapped Lips

If your baby sucks on his/her bottom lip, the area will be all chapped, red, and irritated. Give them a chapstick. Sucking on the lower lip can proceed well into late childhood if not checked.

Reasons Behind this Behavior

Soothing To Your Baby

Soothing To Your Baby

When a baby sucking on bottom lip this is the sign that they soothe themselves. Children undertake different mechanisms to calm down or deal with boredom like thumb sucking or baby biting bottom lip.

Newborns cannot reach their thumb due to a lack of bodily controls and thus find it easier to suck on the lip.


Teething can be very stressful for the baby as it can sometimes cause pain. Around that time, they begin to develop milk teeth which can cause pain and itching in the gum. Hence they chew on their lip.

Try different methods to deal with your child’s teething like providing them teething toys.

Your Child May Be Hungry

If you find your baby sucking lower lip, he/she may be hungry and it is a cue for you to begin feeding. There are several signs to determine if your baby is hungry and this is among the most common ones.


You may not believe but even your baby may be suffering from anxiety. In some children, this could be a sign of nervousness and anxiety.

When Sucking Bottom Lip is a Part of Normal Development


Before beginning solid foods, children suck, bit, and chew all their oral parts like tongue and lips. This is their way of introducing themselves to the concept of chewing. So if you find your baby sucking on bottom lip or tongue, it is a healthy practice. They are just preparing themselves to chew harder food.


Like we already said, teething is very common among children around 6 months. So that makes another reason for you to stop worrying.

Sensory Developmental Milestone

It is a part of any child’s normal sensory and motor development. Children discover their body parts slowly and steadily. Before the mirror stage, a child can conceive itself only in parts and thus can get obsessed with one part or the other. A child fails to distinguish his/her own lip from a pacifier and hence the behavior.

With growth, they develop skills enough to grab other things and then are fascinated with those new discoveries.
