Behaviour

The child frequently puts objects in their mouth, including toys, clothes, or non-food items. This may happen repeatedly across different situations.

What is happening

This behaviour is usually linked to oral sensory seeking.

The child may:

  • Explore objects through the mouth

  • Seek calming or regulating sensations

  • Experience comfort from oral input

It is a way of processing sensory input, not just a habit.

When it appears

  • During play

  • When holding objects

  • In idle moments

  • During stress or self-regulation

What it signals

  • Strong oral sensory need

  • Sensory-seeking behaviour

  • Need for safe alternatives

What works

  • Provide safe oral alternatives

  • Redirect calmly without panic

  • Keep environment safe (remove risky objects)

  • Introduce structured sensory activities

What fails

  • Reacting with fear or anger

  • Snatching objects suddenly

  • Repeatedly saying “don’t do that”

  • Ignoring safety risks

Tools that help

  • Chewable sensory items

  • Safe oral toys

  • Textured teethers

  • Food-based oral activities (when appropriate)

Replace unsafe behaviour with safe alternatives

Real Observation

This behaviour reduces when the child is given consistent and safe oral input options, instead of constant restriction.
