Everything You Need To Know About Infant Finger Sucking

Finger sucking is a seemingly innocent habit. It is the first self-comforting behavior a baby displays, borne out of the basic rooting instinct. Finger sucking can provide infants with a sense of safety and relaxation, serving as a natural response to a variety of feelings including hunger, boredom, anxiety, or fear.

However, it is essential to guide your child toward breaking this habit by the age of four. Learn everything you need to know about infant finger sucking, including why infants suck their fingers, the soothing neurological effects the habit brings, and effective strategies parents can use to help their children quit this behavior.

Why Do Infants Suck Their Fingers or Thumbs?

Babies resort to finger or thumb sucking due to sensations and emotions such as hunger, boredom, anxiety, or fear. The action is a primal instinct rooted in the basic survival mechanism of searching for food. The sucking motion mirrors that of breastfeeding, a comforting reminder to the infant of being fed and nourished.

Thumb and finger sucking can also be a response to boredom, offering a familiar and soothing action that serves as a source of entertainment for the baby. More profoundly, when babies feel anxious or scared, sucking their fingers or thumbs can provide a sense of security and control over their immediate environment.

The neurological impact of this act is soothing and calming. Finger and thumb sucking cause the release of endorphins in the brain that provide a sense of happiness, reward, and comfort. Remarkably, this behavior can even start in the womb, with many ultrasound images capturing fetuses sucking their thumbs, demonstrating that this is one of an infant’s earliest self-comforting actions. Despite its utility in early infancy, it is crucial to encourage children to find alternative self-soothing methods as they grow to prevent any long-term effects.

What Are the Potential Long-Term Effects?

While thumb and finger sucking are standard behaviors in infants and toddlers, it’s essential to be aware that if they persist for too long or become too intense, they can lead to negative consequences. Prolonged and aggressive finger sucking can cause a variety of issues, including the following.

  • Tongue thrust: This refers to when the tongue pushes against or between the teeth while swallowing. This can lead to swallowing and speech difficulties and may even require speech therapy.
  • Dental and jaw malformation: Persistent finger sucking can cause the teeth to become misaligned and may lead to an overbite or underbite. It can also alter the shape of the jaw, leading to structural and appearance issues that may necessitate orthodontic intervention.
  • Speech impediments: The changes in jaw and tongue position can lead to difficulties in speech. Sounds may be pronounced incorrectly, and speech may be less clear, potentially requiring intervention from a speech and language therapist.

These potential issues underline the importance of addressing finger sucking early on, steering your child gently toward other forms of self-soothing and comfort.

When To Step In

Most children naturally outgrow the habit of thumb or finger sucking between the ages of two and four. This is typically the period when they interact more with their environment and learn alternative coping strategies for self-soothing and comfort. However, if the habit persists beyond this age, it becomes crucial for parents to intervene and help their child stop.

The age of four is significant, as this is usually when permanent teeth start to form. Persistent thumb or finger sucking at this age can significantly impact the growth and development of these teeth, leading to dental problems such as misalignment.

Moreover, this is a crucial developmental stage where kids acquire social skills, and a persistent thumb-sucking habit could potentially impact their social interactions. Therefore, parents are advised to take proactive steps to break their child’s finger sucking habit by the age of four.

How To Help a Child Break the Finger Sucking Habit

Learning how to break the finger sucking habit requires patience, understanding, and the right approach. Here are some strategies parents can use to help their children quit this behavior:

  1. Positive reinforcement: Reward your child for not sucking their fingers instead of punishing them when they do. This could be in the form of praise, extra playtime, or small treats. Positive reinforcement encourages the behavior you want to see, making it more likely to happen again.
  2. Substitution: Replace the finger sucking habit with another form of self-comfort, such as a much-loved stuffy or blanket. The goal is to make the new behavior as comforting as the old one, easing the transition away from finger sucking.
  3. Engage their hands: Introducing hobbies or activities that require the use of hands can serve as effective distractions from finger sucking. Drawing, painting, or playing with clay are fun ways to keep your child’s hands busy.
  4. Use a device: If the habit persists, consider using a device like the AeroFinger. It’s a safe, effective tool designed to help children stop the habit by removing the pleasurable sensation of finger sucking.

It’s important to approach this process with understanding and patience, as breaking a habit takes time. Don’t rush your child, and be there to provide support and encouragement along the way.

Thumb or finger sucking is a natural and normal behavior in infants—a form of self-soothing borne out of the rooting instinct that even occurs in the womb. However, if this habit persists beyond the age of four, it can lead to adverse effects such as dental and jaw issues and potential social stigmas. Therefore, taking proactive steps to help your child break this habit before the age of four is crucial.

The AeroFinger provides an excellent solution for this problem. This device acts as a physical barrier, and its design takes away the suction that provides the pleasurable sensation of finger sucking. It’s designed to be safe and effective, allowing for the full use of the child’s hand while helping break the habit. Most children can quit finger sucking, usually within just 30 days of using AeroFinger.

As a parent, your understanding, patience, and positive reinforcement are pivotal during this transition. What you need to know about finger sucking is that the goal is to replace an old habit with new, healthier coping mechanisms while ensuring your child’s comfort and security. Help your child navigate this journey and set a strong foundation for their future growth and development.
