04/04/2024Child Autism / Symptoms of AutismThis article has been written by Jo Condon, our Service Director. Jo has a wealth of experience in the field of autism and has worked with NHS, national government, education and private sector both nationally and internationally.
A common question that we often hear from parents is ‘When do the symptoms of autism start?’.
Autism is a lifelong neurodevelopmental difference, which means that autism has been present from birth.
The way that autism impacts an individual varies, and so does the age at which autistic differences become apparent. For some children, indicators of autism can be seen in the first few months whereas for others it is only when social demands increase that signs are noticed.
Typically, an autism assessment can be carried out from around the developmental age of 18 months. By the age of 5 most autistic children have begun to deviate from their neurotypical peers developmentally; masking and camouflaging behaviours can sometimes mean that the differences are not always obvious.
The pattern of autistic children’s strengths and differences vary from that of their peers. Autistic differences include difficulties with social – emotional social exchanges, communication, play and relationships. Autistic children also engage in behaviours that are more restricted, less flexible or more repetitive than their neurotypical peers and may also process sensory information differently.
Development at 6 months old
Babies typically begin to deliberately make eye contact from around 2 months, and by 6 months they will be able to use eye contact during interaction and be beginning to follow their parent’s gaze to turn toward what they are looking at.
Typically developing babies will have been responding to their parent’s smile with a smile for a couple of months by now, and by 6 months will be beginning to respond to other people’s emotions by crying or laughing; others will be able to tell whether they are happy or annoyed from their facial expression.
They will have begun to babble using ‘ba’, ‘da’ and ‘ga’ sounds.
Gesture will be starting to develop and they may raise their arms to indicate they want to be picked up.
They will be beginning to enjoy parents engaging physically with them, such as laughing when being tickled or bounced, and will be excited when they see familiar people.
Indications of Possible Autism in 6 Month Olds:
Avoiding eye contact
Not responding to a parent’s smile with a smile
Lack of facial expression
Fussiness around less familiar people, or when people interact with them
Lack of enjoyment in physical interaction such as bouncing or tickling
Content to sit and watch items in the environment
Does not turn in response to sounds
Distress around sensory input, such as not liking loud noises, being dresses and undressed or being cuddles
Development at 12 Months Old
By 12 months old, typically developing babies will be pointing at objects and use ‘gaze checking’, that is looking toward their parent to check there are looking at what they are pointing at.
They will be making noises to gain their parent’s attention and will look toward their parent when they call their name.
Language is developing and they will be able to make meaningful sounds such as ‘baba’ or ‘dada’ and may have a few meaningful simple words.
By 12 months, babies typically will shake their head to mean ‘no’ and be able to wave. They will have a full range of facial expression and parents are able to recognise happiness, anger, surprise, fear and disgust from their facial expression.
They will enjoy playing interactive games such as ‘peek a boo’ and ‘round and round the garden’.
Possible Signs of Autism at 12 Months
Lack of pointing
Avoidance of eye contact, or not using eye contact to reference objects
Not responding to name
Lack of interest in people
Dislike of unfamiliar people
Babbling has not developed into meaningful sounds
Not shaking head to mean ‘no’
Lack of facial expression, or facial expression only indicates happiness and annoyance
Lack of interest in, or distress at attempts to play social games
Repetitive movements with hands or arms
Engaging in the same activity or action, such as watching items spinning
Fussy eating, spitting out certain food textures
Development at 18 Months Old
By 18 months, typically children will begin to pull at their parents hand or clothes to get their attention and will be able to direct their parent’s attention to things that they are interested in. They will be able to follow someone else’s point.
They will enjoy interaction and with parents and try to join in with nursery rhymes.
They will be able to say several meaningful words, such as ‘cup’, ‘dog’ or ‘bus’ and will be able to follow basic instructions relating to things that are out of sight, such as ‘fetch your coat’.
Gesture continues to develop and they will be able to clap, blow kisses, indicate ‘shh’ with a finger on lips and nod their head to mean ‘yes’.
At this age, children will be regularly offering toys to other people and will begin to execute pretend actions with their toys such as feeding a doll or acting out short scenarios with toy cars. They will begin to copy some of their parent’s actions, such as wiping the tray of their high chair.
Possible Signs of Autism at 18 Months

Development at 2 Years Old
At around the age of 2 years, typically developing children will be able to put two or more words together and will ask two word questions for example, “Where daddy?”.
They will be able to follow simple commands and will use a range of non-verbal methods of communication, including gesture, eye contact and facial expression.
At this age, typically developing children will begin to engage in simple pretend play sequences. They will imitate their parents’ actions, such as pretending to use a toy vacuum cleaner.
They will begin to sow an interest in other children, though will be more likely to play alongside them at this age.

Development at 5 Years Old
By the age of 5, typically developing children will be using sentences to communicate and will be able to tell their parents about their day and things that interest them. They will be keen to direct their parents’ attention to things they do and things that they see. They will use a range of verbal and non-verbal communication to interact with familiar and unfamiliar people.
Typically developing children will be able to identify and share their basic emotional state, for example, “I am sad…”
They will be enjoying a range of play, including pretend play, both on their own and with other children. They will be able to engage in group games such as ‘tag’.
Typically developing children will be showing more independence, will enjoy new experiences and will be able to leave their parents with little support to do so.
