You might have noticed your child putting toys, clothes, or even their own hands in their mouth — or licking surfaces and objects around them. While this behavior might seem unusual or worrying, it’s actually quite common, especially for children who have sensory processing differences or are feeling overwhelmed.
Mouthing and licking are ways children explore their world, self-soothe, and regulate their nervous system. These behaviors often increase during times of stress or dysregulation, signaling your child’s need for comfort or sensory input.
Why Do Kids Mouth or Lick Things?
- Sensory Exploration: Babies and toddlers use their mouths to learn about textures, tastes, and objects — this continues for some children beyond early childhood, especially if other senses feel overloaded.
- Sensory Seeking: Mouth and tongue provide rich sensory input. When other senses feel under-stimulated or overwhelmed, mouthing can help bring calm or focus.
- Self-Regulation: During stressful moments or transitions, mouthing or licking can serve as a calming strategy, much like rocking or fidgeting.
- Oral Motor Needs: Some children have oral motor delays or needs and benefit from exercises that provide oral input.
When Mouthing or Licking Increases
During times of:
- Anxiety or frustration
- Fatigue or overstimulation
- Change in routine or environment
children might turn more often to mouthing or licking as a way to soothe themselves or regain control.
Recognizing this can help you respond with compassion and effective support rather than frustration.
How to Support and Redirect Mouthing/Licking Behavior
While mouthing objects is natural, it’s important to gently guide your child towards safer or more appropriate ways to meet their sensory needs.
1. Provide Safe Oral Sensory Tools
- Chewy necklaces or bracelets designed for sensory input
- Chewable toys made for oral motor needs
- Crunchy or chewy snacks (if diet allows) that provide oral stimulation
2. Encourage Oral Motor Activities
- Blowing bubbles or blowing through straws
- Chewing gum (age-appropriate)
- Using whistles, harmonicas, or kazoo toys
3. Create a Calm Environment During Stress
- Notice when mouthing increases and offer calming activities like deep pressure or heavy work first
- Use simple, soothing words to help your child feel safe
4. Redirect Gently and Consistently
- When you see your child mouthing unsafe objects, calmly redirect them to a safe chew or activity without punishment or shaming
- Use visuals or social stories to explain what’s okay to mouth and what isn’t
Mouthing and licking are natural behaviors that often signal your child’s sensory and emotional needs — especially when they’re feeling stressed or dysregulated. By understanding these signals and offering safe, satisfying alternatives, you can support your child’s comfort and development in a kind, effective way.
