Posted November 5, 2025 Updated November 5, 2025 Author: Lucia Alvarez, MSc Reviewed by: Dr. Rebecca Fernandez, MBBS

Yes, sleep problems in autism are common and can often be one of the early autism signs. Many children with autism experience difficulty with sleep, including trouble falling asleep, staying asleep, or waking up frequently during the night. These sleep issues are more than just typical toddler sleep disturbances; they are often linked to the sensory sensitivities, emotional regulation challenges, and irregular routines that are characteristic of autism.

Children with autism may struggle with the sensory experiences associated with bedtime, such as the feeling of certain sheets or the noise of a fan. Additionally, irregular sleep patterns can be related to developmental symptoms like anxiety, difficulty with self-regulation, or a need for routine.

How Sleep Problems in Autism Manifest

This is how sleep problems commonly present in autism:

Difficulty Falling Asleep:

Many children with autism may take longer to fall asleep due to sensory sensitivities or an inability to calm themselves down at night.

Frequent Night Wakings:

Children with autism may wake up multiple times throughout the night, often due to anxiety or discomfort caused by sensory overload.

Irregular Sleep Patterns:

Some children with autism may have inconsistent sleep schedules, making it difficult for parents to establish a healthy bedtime routine.

Recognising sleep problems in autism as an early symptom is crucial for parents and caregivers to seek appropriate support. Addressing sleep issues early can help improve overall well-being and daytime functioning.
