A Parent’s Guide to Faecal Smearing in Autism and Sensory Processing Disorder (SPD)

If you’re reading this, chances are you’ve experienced the overwhelming challenge of faecal smearing — standing in the middle of a mess, feeling defeated, and wondering if you’re the only parent dealing with cleaning faeces off walls, floors, toys, or clothes.

First and foremost: You are not alone.

Faecal smearing, also known as faecal play or scatolia, is common among children with autism spectrum disorder (ASD) and sensory processing disorder (SPD). While it can feel exhausting and confusing, many families have faced it and come through stronger.

This guide offers understanding, compassion, and practical tools to help you manage and cope with faecal smearing in your child.

Why Does Faecal Smearing Happen in Autism and SPD?

Understanding the reasons behind faecal smearing can ease some of the emotional burden. There isn’t always a single cause, but common reasons include:

● Sensory Exploration: Children with autism or SPD may seek out different textures, smells,
and sensations. Faeces may provide a unique sensory input they find interesting or regulating.
● Communication: For nonverbal or minimally verbal children, faecal smearing may be a way to express feelings such as distress, frustration, or a need for attention.
● Toileting Issues: Smearing can occur during potty training or when a child experiences
constipation or discomfort.
● Routine and Repetition: The behavior might become a ritual, occurring regularly or
triggered by specific circumstances.
● Lack of Awareness: Some children might not fully grasp social norms around toileting and cleanliness, especially if they don’t feel discomfort from feces on their skin.
● Responses from Adults: Children with autism may be fascinated by adult reactions, which
can reinforce the behavior if responses are unpredictable or extreme.

Practical Tips for Managing Faecal Smearing

Every child is different, but here are strategies that have helped many families cope with faecal smearing:

        1. Rule Out Medical Causes

Track bowel movements using tools like the Bristol Stool Chart and keep a diary. Consult your child’s pediatrician or a gastrointestinal specialist to rule out constipation, digestive problems, or skin irritations. Addressing medical issues can significantly reduce incidents.

       2. Use Protective Clothing

Consider footed pajamas, snug onesies, or anti-strip bodysuits with zippers out of reach. These can limit access to feces during naps or overnight, reducing clean-up stress while working on behavior.

     3. Establish a Calm Clean-Up Routine 

Stay calm and neutral during clean-up to avoid turning it into a power struggle. Use minimal words and eye contact, moving slowly and calmly. If appropriate, involve your child in cleaning to teach natural consequences without punishment.

     4. Provide Alternative Sensory Outlets

Offer safe sensory play options like slime, kinetic sand, finger paints, squishy toys, or shaving cream to satisfy sensory needs without smearing.

     5. Use Visual Supports and Social Stories

Visual schedules and social stories tailored to your child’s comprehension can explain bathroom routines and appropriate behavior. Many parents share resources online for easy, affordable tools.

     6. Positive Reinforcement

Praise and reward positive steps, such as using the toilet correctly or resisting smearing urges. Use specific praise and small rewards like stickers or favorite videos.

    7. Seek Professional Support

Occupational therapists (OTs), behavioral therapists, or developmental pediatricians can help assess sensory needs and develop tailored plans. Your GP can refer you to local disability teams or hubs.

Encouragement for the Hard Days

Faecal smearing is tough, exhausting, and isolating. You may feel overwhelmed or like a failure, but remember:

● You are not failing.
● You are showing incredible patience, love, and resilience.

● This phase will improve over time, though progress may include setbacks.
● Asking for help and celebrating small wins are crucial steps.

With time, understanding, and support, you and your child will get through this.

Final Thoughts

Faecal smearing in children with autism and sensory processing disorder is a challenging behavior, but it is manageable. You are doing an incredible job navigating this difficult journey with love and strength. Be kind to yourself, seek help when needed, and remember you are not alone.
