Understanding the phenomenon

Before we dive into the depths of lip sucking, let’s take a moment to appreciate the uniqueness of this behavior. Picture your little one, their tiny lips forming a perfect seal around the lower lip, as if they’re preparing for a tiny kiss. It’s utterly endearing and hard to resist the urge to join in on the fun.

What Causes Baby Sucking on Bottom Lip

Babies engage in various behaviors as they explore their bodies and develop new skills. Sucking on the bottom lip is one of these behaviors, and it can have several underlying causes. Understanding these causes can provide valuable insight into why your baby engages in this behavior. Here are some common reasons:


Babies have a natural instinct to soothe themselves. Inside the womb, they often suck their thumbs or fingers for comfort. Once born, it becomes more challenging for babies to access their thumbs or fingers, leading them to find alternative ways to self-soothe. Sucking on the bottom lip can serve as a substitute for thumb-sucking or finger-sucking, providing a sense of comfort and security.


Teething is a significant milestone in a baby’s development. As their teeth begin to emerge, babies may experience discomfort and soreness in their gums. To alleviate this discomfort, they may bite or suck on objects, including their bottom lip. Teething rings, chilled fruits, and other teething remedies can help provide relief and reduce the need for lip-sucking.

Hunger or Food Curiosity

Babies are naturally curious about the world around them, including the food their parents eat. When they see you eating, they may mimic the action by biting, sucking, and smacking their lips. This behavior can indicate their interest in trying solid foods. If your baby is ready for solid foods, consider introducing age-appropriate purees or soft foods to satisfy their curiosity.

Exploration and Sensory Development

Babies explore the world through their senses, and their lips are no exception. Sucking on their bottom lip can be a way for them to understand their body and the sensations it provides. It can also be a part of their sensory developmental milestones, as they learn about different textures and movements

Is Baby Sucking on Bottom Lip Normal?

Rest assured, baby lip-sucking is generally considered normal and not a cause for concern. It is a common behavior exhibited by many infants as they navigate the early stages of their development. Most babies outgrow this behavior on their own as they become more adept at self-soothing and exploring other ways to engage with their environment.

When to Be Concerned About Baby Sucking on Bottom Lip

While baby lip-sucking is typically harmless, there are instances where it may warrant further attention. Here are a few situations to consider:

Persistent Lip-Sucking Beyond 1 Year

If your baby continues to suck on their bottom lip beyond the age of one year, it may be worth discussing with their pediatrician. Prolonged and persistent lip-sucking could indicate an underlying issue that requires professional evaluation. The pediatrician can assess the situation and provide guidance on how to address the behavior if necessary.

Physical Symptoms or Injuries

In some cases, excessive lip-sucking can lead to physical symptoms such as chapped lips, blisters, or even bruises. If you notice any signs of irritation or injury on your baby’s lip, it’s important to address the issue. Applying a baby-safe lip balm or coconut oil can help soothe minor lip irritation. However, if the symptoms persist or worsen, consult with your pediatrician for further advice.

Speech and Dental Development Concerns

Extended and intense lip-sucking may have implications for speech and dental development. Children who engage in prolonged thumb-sucking or lip-sucking may experience dental issues, such as malocclusion (abnormal alignment of teeth) or speech problems. If you suspect that your child’s lip-sucking behavior is negatively impacting their oral health or speech development, consult with a pediatric dentist or speech therapist for appropriate interventions

Tips for parents to deal with Baby Sucking on Bottom Lip

In most cases, baby lip-sucking is a temporary behavior that resolves naturally over time. However, if you feel the need to address the behavior, here are some strategies you can try:

Provide Alternative Soothing Methods

Since lip-sucking is often a form of self-soothing, it can be helpful to introduce alternative soothing techniques. Offer your baby a pacifier or a soft toy to suck on, redirecting their attention away from their bottom lip. These alternatives can provide comfort and help them develop new self-soothing habits.

Maintain a Consistent Feeding Schedule

If your baby’s lip-sucking behavior seems to be related to hunger, ensure that you maintain a consistent feeding schedule. By providing regular and adequate feedings, you can reduce the likelihood of lip-sucking as a signal of hunger. Observe your baby’s feeding patterns and adjust the schedule accordingly to meet their needs.

Introduce Age-Appropriate Solid Foods

If your baby’s lip-sucking behavior arises from curiosity about food, consider introducing age-appropriate solid foods. Consult with your pediatrician to determine when it is appropriate to start introducing solids and which foods are safe for your baby. By satisfying their curiosity and allowing them to explore new tastes and textures, you may reduce their inclination to suck on their bottom lip.

Distraction and Engaging Activities

Engaging your baby in stimulating activities can divert their attention away from lip-sucking. Take them outdoors for a walk, play with them using age-appropriate toys, or read to them. Providing a variety of engaging experiences can help redirect their focus and encourage the development of new interests and behaviors

When to consult a pediatrician

While lip sucking is generally a harmless behavior, there are instances where seeking professional advice is warranted. Pay attention to any unusual changes in your baby’s lip appearance, such as discoloration, swelling, or sores. These could be signs of an underlying issue that requires medical attention.

Consistent lip sucking beyond infancy, especially when it begins to interfere with normal activities like eating or speaking, should also be discussed with your pediatrician. They can assess your baby’s overall development and offer guidance specific to their needs.
