Early signs of autism in babies (6 months to one year) may include: Reacting in an unexpected way to new faces. Rarely smiling in social situations. Making little or no eye contact.
Some signs of autism can appear during infancy, such as:
- limited eye contact.
- lack of gesturing or pointing.
- absence of joint attention.
- no response to hearing their name.
- muted emotion in facial expression.
- lack or loss of language.
In general, a baby will show signs of ASD between the ages of 12 and 24 months. However, signs of ASD in babies can develop outside of this age range. The Centers for Disease Control and Prevention (CDC) note that a baby can show signs of ASD from the age of 9 months .
The symptoms to look out for in children for suspected autism are:
- Delayed milestones.
- A socially awkward child.
- The child who has trouble with verbal and nonverbal communication.
Signs of autism in children
- not responding to their name.
- avoiding eye contact.
- not smiling when you smile at them.
- getting very upset if they do not like a certain taste, smell or sound.
- repetitive movements, such as flapping their hands, flicking their fingers or rocking their body.
- not talking as much as other children.
At 6 months, your baby will start using sounds to express emotion. She/he may mimic sounds she/he hears, like "ma,” “da,” “ah,” “oh" and even "no!" Your little one will begin to recognize familiar faces, reach and grasp for toys and will soon be crawling — start preparing your home (and yourself) for a mobile child!
At 18 months, the babies later diagnosed with autism continued to smile less than the other baby sibs. Surprisingly, at this age, typically developing infants actually smile less than the baby sibs without autism and slightly more than those with the disorder (although neither difference is statistically significant).
Autistic children can have particular sleep and settling difficulties, including: irregular sleeping and waking patterns – for example, lying awake until very late or waking very early in the morning. sleeping much less than expected for their age, or being awake for more than an hour during the night.
Many children with autism spectrum disorder (ASD) show developmental differences when they are babies—especially in their social and language skills. Because they usually sit, crawl, and walk on time, less obvious differences in the development of body gestures, pretend play, and social language often go unnoticed.
Beginning as young as 2 months of age, infants later diagnosed with autism show a steady decline in eye contact that might be the earliest marker yet for the disorder.
Conclusion: The rate of IC is not increased in patients with ASD, but infants with excessive crying should be very thoroughly evaluated before being diagnosed with IC. In particular, persistent crying in infants (i.e. excessive crying with late onset and long duration) may be an early symptom of ASD.
Most babies will begin laughing around month three or four.
Between 1 and 2 years of age, baby sibs who go on to develop autism have more trouble with focus and with controlling their emotions, the study found. They are also less likely to smile, cuddle or laugh and more likely to seem sad or shy than typical children.
People with autism sometimes may have physical symptoms, including digestive problems such as constipation and sleep problems. Children may have poor coordination of the large muscles used for running and climbing, or the smaller muscles of the hand. About a third of people with autism also have seizures.
You might notice your baby beginning to scoot, rock back and forth, or even crawl across the room. Some babies this age can pull themselves to a standing position. Soon your baby might cruise along the edge of the couch or coffee table. Improved hand-eye coordination.
Able to lift chest and head while on stomach, holding the weight on hands (often occurs by 4 months) Able to pick up a dropped object. Able to roll from back to stomach (by 7 months) Able to sit in a high chair with a straight back.
Although typically developing children generally produce their first words between 12 and 18 months old (Tager-Flusberg et al. 2009; Zubrick et al. 2007), children with ASD are reported to do so at an average age of 36 months (Howlin 2003).
While your baby may recognize their name as early as 4 to 6 months, saying their name and the names of others may take until somewhere between 18 months and 24 months. Your baby saying their full name at your request is a milestone they'll likely reach between 2 and 3 years old.
Many babies laugh out loud for the first time when they're 3 or 4 months old, although others might take a little longer to share their first chuckle. Your baby's first laugh might be inspired by something as simple as seeing a favorite toy, pet or person (that would be you!).
At 6 months old, babies will rock back and forth on hands and knees. This is a building block to crawling. As the child rocks, he may start to crawl backward before moving forward. By 9 months old, babies typically creep and crawl.
The earliest social feeding behavior, breastfeeding, has been described with respect to duration, but neither latch nor feeding patterns have been described in infants later diagnosed with ASD (Al-Farsi et al., 2012; Schultz et al., 2006).
Has difficulty getting things to his mouth. Seems stiff or floppy. 6 months: Doesn't watch things as they move, smile at people, “coo” or make sounds, bring objects to her mouth, or push down with her legs when her feet are placed on a hard surface.
Autistic children aren't crying, wailing, or flailing to get at us somehow. They're crying because it's what their bodies need to do in that moment to release tension and emotion from feeling overwhelmed with emotions or sensory stimulations.
Rarely shares enjoyment with you. Babies readily share enjoyment with you by smiling or laughing and looking at you. Some children with autism smile to show they're happy but don't share their enjoyment. Others show little facial expression or have flat affect and rarely smile so you may not know when they're happy.
