Yes, a child can be assessed for autism from the age of 2. We offer private autism assessments for 2-year-olds at all of our clinics, following NICE guidance, with a play-based observation in clinic and a detailed report with recommendations for home and nursery.
Noticing that a child is showing developmental differences is understandably worrying for parents, who want answers to be able to help their child in the best possible way. Many families reach out to healthcare professionals with their concerns only to be told that their child is too young to be assessed or that the waiting times for assessments are many years long. Being told to ‘watch and wait’ can add to concerns and cause much frustration for families.
Parents choosing the private route for answers can find it difficult to locate a service that assesses children for autism in the early years; we undertake private autism assessments for 2-year-olds at all of our clinics.
Signs of autism are not always obvious in 2-year-olds, and many children are identified when they are older.
Autistic children present with a distinct pattern of behaviours which includes differences in social interaction and communication, repetitive behaviours and interests and/or sensory issues. A child presenting with this pattern of behaviours should be assessed for autism as evidence suggests that early identification and intervention improve outcomes for children on the spectrum.
In this article, our Director, Jo Condon, explains the importance of early identification, signs of autism in 2-year-olds and what to expect from the assessment process.
Can autism be diagnosed at age 2?
In some cases, autism can be diagnosed as early as 18 months, but assessments are usually offered from the age of 2. Autism affects children in different ways, and not every child shows obvious signs in the early years, so many are not identified until later in childhood.
Children with more noticeable developmental differences, such as a speech delay or a loss of words they used to say, tend to be picked up earlier.
Why is early identification important?
Often parents who query symptoms of autism with healthcare or education professionals are met with negative viewpoints about ‘labelling’ their child at such a young age. Those with experience in the field of autism understand the importance of an autism diagnosis. Understanding a child’s autism profile helps with recognition of their differences and support needs.
Research indicates that early identification, support and intervention can significantly improve outcomes for autistic children.
Early identification helps:
- Ensure that parents have a clear understanding of their child’s strengths and needs
- Wider family members to recognise the child’s differences
- Make the child’s early years setting or a setting they will attend in the future aware of their needs in order to provide appropriate intervention
- Support the development of social and communication skills
- Families to demonstrate the child’s needs to be able to access additional support and financial assistance
- Help nursery and school prepare for your child’s needs before they start, including applying for an EHCP if your child needs one
What behaviours are common in autistic 2-year-olds?
The way in which autistic differences impact a child varies. Autistic 2-year-olds often present with difficulties associated with autism that cause them distress and place much stress on the family and home environment, including:
- Sleep issues, including difficulty settling to sleep, night waking or seemingly only needing a few hours of sleep to get by
- Difficulties regulating emotions, experiencing meltdowns which appear more frequent or more extreme than other 2-year-olds
- Having a dislike of wearing clothes, removing clothes, distress when being dressed or having nappy changed
- Eating difficulties, eating a limited amount or range of food, refusing to eat or only eating with much encouragement
- Distress around unfamiliar people or seeming to take a dislike to particular people, refusing to stay with others and distress on separation from main carers
- Needing constant supervision due to climbing and jumping off things, placing non-edible objects in their mouths and / or not appearing to feel pain
What are the signs of autism in a 2-year-old?
When assessing for autism in 2-year-olds we look for a pattern of differences that include difficulties with communication and interaction and also involve repetitive actions or behaviours and/or sensory differences.
Whilst some behaviours can be seen in isolation in typically developing children, when a child is showing differences in development across the areas of social interaction and communication and is also showing restricted or repetitive behaviours and sensory differences an autism assessment is recommended.
We can undertake a private autism assessment for a 2-year-old at any of our clinics.
Autism impacts a 2-year-old’s ability to communicate and interact with others, causes a child to engage in play differently to their peers and causes them to engage in repetitive behaviours. Many autistic children also have sensory differences.
Typical differences in interaction and play, repetitive behaviours and sensory issues are outlined below:
Communication and interaction
- Not using words and / or phrases
- Using only words and phrases that are repeated from others, television programmes or videos
- Not responding to name
- Not smiling socially
- Avoiding eye contact
- Not using gestures such as blowing kisses or giving a thumbs up
- Not pointing to indicate needs or interest
- Being unable to follow a point
- Hand leading and using another’s hand to complete actions on objects as a way of getting needs met
- Being unable to make needs known through verbal or non-verbal means
- Lack of interest in other children
Differences in play
- Not engaging in pretend play, such as feeding a doll
- Only engaging in pretend actions that are copied or demonstrated by others first
- Making patterns with toys rather than engaging in typical play, such as lining up cars or teddies
- Enjoying sorting and organising, emptying and refilling boxes, ordering numbers and letters
- Engaging in repetitive play, such as pushing buttons or stacking blocks and knocking them over
- Becoming focused on part of a toy or object, or wanting to take toys apart to understand how they work
- Being interested in sensory aspects of toys, for example, turning cars over and spinning the wheels
- Choosing to always play with the same toys or engage in the same activity
- Watching a limited range of television programmes or watching the same video over again
- Enjoying a TV programme or character, but showing no interest in the associated toys
Repetitive body movements
- Moving fingers in a repetitive way
- Twirling, clenching or flapping hands
- Making repetitive noises or sounds
- Tapping or pinching own or other’s body
- Jumping or bouncing
- Spinning self
- Posturing – holding body or parts of body in a tense way
Sensory differences
- Difficulties with loud noises or busy places
- Dislike of certain fabrics or textures
- Dislikes wearing clothes or changing clothes or nappy
- Fussy eater, or lack of interest in eating
- Watching lights or light patterns
- Distress at having hair washed, brushed or cut
- Resistance to having teeth brushed
- Placing inedible objects in mouth
- Licking or sniffing people or items in the environment
- Climbing excessively
- Jumping or bouncing off objects and furniture
- Constantly wanting to be swung or rocked
If a child is showing patterns of differences in their development similar to those outlined above, they should be assessed for autism so that their needs are identified in a timely way.
Recognise several of these signs in your child?
How do I know if my child needs an assessment?
If you are unsure as to whether an autism assessment is needed, we can help. One of our clinicians can discuss your child’s behaviours with you and can send you a screening tool to complete. A screening tool is an evidence-based questionnaire which is scored in accordance with the responses given. These can help a professional understand the number and level of autism characteristics present.
Our screening is free. For young children, we usually send you the M-CHAT, a questionnaire designed for toddlers. Once you have completed it, we will talk through your answers and any other concerns with you, and advise whether an autism assessment is recommended. Get in touch with us to request it.
Why can it be hard to get an NHS autism assessment for a 2-year-old?
Each local NHS autism pathway has its own referral criteria, which set out who can be referred, when and by whom. In some areas, children need to be five or older before they can be referred, and in others only certain professionals can make a referral.
Waiting times for children are also long. Birmingham Community Healthcare, for example, currently reports that children wait at least 34 months for an autism assessment, and Sheffield Children’s NHS Foundation Trust estimates around 2 years for pre-school children.
This is why more parents of very young children are choosing a private assessment, so their child’s needs are understood before they start school.
What happens in an autism assessment for a 2-year-old?
A private autism assessment involves multiple steps to ensure a comprehensive assessment, clear outcome and robust report are achieved. Our process follows the NICE guidelines, the standard expected from the NHS.
Background information gathering
We will gather information about concerns, behaviours and some aspects of development from you, and also your child’s early years setting, if they attend one.
You will have a dedicated clinical assessment coordinator, who will explain each step and be your point of contact throughout.
Detailed diagnostic interview
Using the Autism Diagnostic Interview-Revised (ADI-R), we will meet with you by video link to ascertain what behaviours and characteristics your child is showing and has shown in the past.
Observation
We will use the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) to complete a semi-structured observation of your child in our clinic. For 2-year-olds, we use the module best suited to your child’s age and language, usually the Toddler Module or Module 1, which involves lots of play activities such as bubbles and pop-up toys. You will be able to stay with your child for the session.
Multidisciplinary review
When we have completed our sessions and have gathered all the information we need, we will meet as a team to consider whether your child meets the diagnostic criteria. We then complete an extensive report, outlining all the information we have gathered and recommendations for next steps.
Report and feedback
We will then issue your report and diagnostic outcome and arrange a feedback session with one of the clinicians who was involved in your assessment.
In this session, you can ask any questions you have in relation to the assessment and report, or seek advice about specific issues such as sleep, eating or behaviours.
Why choose a private assessment for a 2-year-old?
Opting for a private assessment offers several advantages, including reduced waiting times, a personalised approach and clearer communication throughout the process.
NHS England figures from June 2026 show almost 295,000 people with an open referral for a suspected autism assessment, most of them waiting more than 13 weeks. With a private assessment, you can usually begin within 2 to 3 weeks.
A private autism assessment for a child costs £2,095, with the observation carried out in one of our clinics. Our cost page sets out exactly what is included.
Private autism assessment services offer a more personalised approach to your assessment. You are usually able to speak to an expert ahead of arranging an assessment to make sure an assessment is warranted; you may be asked to complete screening tools to help identify the child’s pattern of behaviours.
From start to finish, your assessment will be coordinated with you, and the team will take your preferences into account. You will feel listened to and will be able to get your queries answered in a timely way.
Many parents have concerns before the assessment. Common concerns around autism assessments for 2-year-olds include worries about the child not engaging in the assessment or typical behaviours seen at home not being observed in the clinic. You can discuss concerns with the team before your assessment sessions so that you are reassured, and your child’s assessor is aware of your concerns.
An autism assessment not only provides a diagnostic outcome but also summarises a profile of your child, which can help you and others around you respond to their needs and support their development. Following an assessment with us for your 2-year-old, you will be provided with recommendations about approaches that will help your child on a day-to-day basis.
Summary
Investing in a private autism assessment for a 2-year-old can help parents understand the child’s strengths and needs and can be the first step in ensuring the child gets appropriate support.
Children who present with the specific pattern of behaviours outlined above should be assessed for autism. Screening tools are also a useful way of understanding whether an assessment is needed.
By choosing a NICE-compliant autism assessment service for an autism assessment for a 2-year-old, parents can be assured of a timely assessment that can be relied upon by public bodies, such as the NHS.
Early diagnosis, understanding and support can make a significant difference in the child’s long-term outcomes, helping them reach their full potential.
