In addition to the early signs of autism that I mentioned earlier, there are some developmental milestones that parents can look out for in children to identify potential signs of autism. Here are some of them: 1. Lack of social smiling: By 6 weeks of age, most infants will start to respond to social stimuli with a smile. Infants who do not show social smiling by 6 months of age may be at risk for autism. 2. Lack of pointing: Typically developing infants will start to point to objects or people they are interested in around 9-12 months of age. Children with autism may not point or may use pointing in an unusual way. 3. Lack of response to name: Typically developing infants will respond to their name by turning their head or looking in the direction of the sound. Children with autism may not respond to their name or may have a delayed response. 4. Lack of babbling: By 6 months of age, most infants will start to babble and make sounds. Children with autism may have delayed or absent babbling. 5. Delayed motor milestones: Children with autism may have delayed motor milestones such as crawling, walking, or running. 6. Lack of imitative play: Typically developing infants will imitate others' actions, such as clapping or waving, by 9-12 months of age. Children with autism may have difficulty with imitative play. It's important to note that these developmental milestones are general guidelines, and not all children with autism will exhibit delays in these areas. However, if parents or caregivers have concerns about their child's development, they should discuss them with their child's pediatrician. Early intervention and support can greatly benefit children with autism and their families.
