Toddler putting fingers in mouth

As parents, it can be alarming to see our toddlers putting their fingers in their mouths. However, this behavior is actually quite common among young children, and is often a normal part of their development. In this article, we will explore why toddlers put their fingers in their mouths and what parents can do to help encourage healthy habits.

Why Do Toddlers Put Their Fingers in Their Mouths?

There are a number of reasons why toddlers put their fingers in their mouths. Here are a few of the most common:

  1. Teething: Teething is a common cause of finger-sucking in toddlers. When new teeth are erupting, the pressure on the gums can be uncomfortable, and sucking on fingers can provide relief.
  2. Exploration: Toddlers are naturally curious, and they often use their mouths to explore their environment. This includes putting their fingers, toys, and other objects in their mouths to taste, feel, and experience them.
  3. Comfort: For many toddlers, finger-sucking is a comforting behavior. It can help them feel secure and soothe themselves when they are upset or anxious.
  4. Boredom: Toddlers may put their fingers in their mouths out of boredom, especially if they don’t have any other toys or activities to occupy them.
  5. Habit: Finger-sucking can become a habit for some toddlers, especially if they have been doing it for a long time.

Is Finger-Sucking Harmful?

In most cases, finger-sucking is not harmful to toddlers. It is a normal part of their development, and many children grow out of it on their own. However, there are some potential risks associated with finger-sucking, especially if the behavior continues past the toddler years.

One concern is that finger-sucking can lead to dental problems, such as an overbite or an open bite. This is because prolonged sucking can cause the front teeth to push forward or become misaligned. Additionally, finger-sucking can also increase the risk of infection, especially if the child’s hands are not clean.

How Can Parents Encourage Healthy Habits?

If you are concerned about your toddler’s finger-sucking habit, there are several things you can do to help encourage healthy habits:

  1. Offer alternatives: Provide your child with other things to suck or chew on, such as teething toys, pacifiers, or chewy snacks. This can help redirect their urge to suck on their fingers.
  2. Be patient: Remember that finger-sucking is a natural behavior, and it may take some time for your child to grow out of it. Avoid scolding or punishing your child for the behavior, as this can create anxiety and make the habit worse.
  3. Set limits: If your child’s finger-sucking habit is causing dental problems or other issues, you may need to set limits. For example, you could encourage your child to only suck on their fingers at home, or during naptime and bedtime.
  4. Be a role model: Children often learn by example, so be sure to model healthy habits yourself. Avoid sucking on your own fingers or biting your nails in front of your child.
  5. Keep hands clean: Encourage your child to wash their hands regularly, especially before eating or putting their fingers in their mouths. This can help reduce the risk of infection.


Toddlers putting their fingers in their mouths is a common behavior that is usually harmless. However, if you are concerned about your child’s finger-sucking habit, there are several things you can do to encourage healthy habits. By offering alternatives, being patient, setting limits, being a role model, and keeping hands clean, you can help your child develop healthy habits and avoid potential risks associated with finger-sucking.
