Tiny Mouths, Big Feelings: Supporting Your Child’s Sensory Needs

Children often display puzzling and sometimes overwhelming oral sensory behaviours, such as chewing on shirt collars or gagging at certain textures, which is considered unusual if it continues after the age of 2. These behaviours are particularly common among children with Autism Spectrum Disorder (ASD), who may have specific oral sensory preferences, but they can also be observed in children without ASD. This post aims to help parents understand their children's needs and find effective ways to accommodate them.

What Are Oral Sensory Behaviours?

Children use their mouths for more than eating—they explore, self-soothe, and process the world around them. Oral sensory behaviours typically fall into two groups:

Sensory Seekers: These children crave oral input; it helps them feel calm and focused. Here are some common signs that your child may be a seeker:

• Chews on pencils, shirt collars, or nails  
• Puts objects into their mouths that are not meant to be there  
• Enjoys chewy or crunchy foods like gummy candies or chips 
• Prefers sour, savoury or spicy foods
• Sucks on their thumbs

Sensory Avoiders: These children are hypersensitive to oral input. They may gag easily, avoid certain textures or temperatures, or become distressed during mealtimes. Here are some common signs that your child may be an avoider:

• Avoids mealtimes altogether
• Prefers a limited variety of food types or textures
• Prefers blander foods
• Avoids brushing teeth regularly.
• Gags easily when eating, often requiring a drink to help swallow food

Oral sensory behaviours—whether seeking or avoiding—are not “bad habits” to eliminate, but signals of how a child is processing their world. Instead of trying to suppress these behaviours, it’s more effective (and compassionate) to redirect them toward safer, more appropriate alternatives. 

For oral avoiders, progress starts with trust. These children benefit from gradual, step-by-step desensitisation, paired with encouragement and positive reinforcement. Even small wins—like tolerating a new food nearby—deserve celebration.

Practical Tips for Parents

💡 For Sensory Seekers:

• Offer safe chewable items like silicone necklaces or sensory pencil toppers.
• Provide crunchy or chewy snacks (e.g., pretzels, bagels, dried fruit) throughout the day.
• Try blowing bubbles, whistles, or using straws for calming oral input.
• For older kids, chewing gum may be an effective alternative

💡 For Sensory Avoiders:

• Introduce new textures gradually—try placing a new food next to a preferred one.
• Let your child explore with food through play (e.g., painting with yoghurt).
• Respect their limits. Forcing them can increase anxiety and aversion.
• Give your child plenty of time for prewarning and warm-up.
• For kids who avoid brushing, use a warm, soft towel to gently massage around their mouths and desensitise before brushing.

Children who chew, bite, or avoid certain foods are not being "difficult"; they are expressing their sensory needs. Some seek extra oral input, while others are sensitive to sensations. Instead of stopping these behaviours, we can guide them with safe alternatives for seekers and gentle desensitisation for avoiders. With patience and the right strategies, families can help their children thrive.
