If you are wondering when autism screening is done, what age it is recommended, or how screening milestones by age fit into regular checkups, this page can help. Learn what typically happens at 18 months and 24 months, then answer a few questions for personalized guidance based on your child’s screening timeline.
Start with the timing of your child’s 18-month and 24-month visits so we can offer guidance that matches your family’s next step.
Autism screening is commonly recommended during routine well-child visits, especially at 18 months and 24 months. These milestone visits are important because they align with a stage of rapid social, communication, and behavioral development. Pediatric care often includes general developmental screening along with autism-specific screening at these ages, even when a child seems to be developing well. If a parent, caregiver, or clinician has concerns earlier or later, screening may also be discussed outside those standard visits.
Autism screening at 18 months is a common recommendation during a toddler well visit. This is often one of the first key checkpoints for reviewing social interaction, communication, play, and behavior patterns.
Autism screening at 24 months is another recommended milestone. This follow-up timing helps capture developmental patterns that may become clearer as language, social engagement, and behavior continue to develop.
If you have concerns before or after these visits, bring them up with your child’s clinician. Autism developmental screening milestones guide routine care, but parents do not need to wait for a specific birthday to ask questions.
Screening helps identify whether a child may benefit from closer follow-up, additional developmental review, or early support. It is a starting point for discussion, not a label by itself.
For many families, autism screening for an 18 month old or autism screening for a 2 year old happens as part of a standard well visit, making it easier to review development in context.
Whether your child has already been screened, has a visit coming up, or you are not sure what was done, understanding the recommended timing can make it easier to plan what to ask at the next appointment.
Many parents do not remember the exact name of every questionnaire used at a well visit. If you are unsure whether autism screening was completed at 18 months or 24 months, that is common. You can check your visit summary, patient portal, or ask your child’s pediatric office directly. Our assessment can help you think through your child’s age, visit history, and what kind of follow-up question may be most useful to ask next.
Parents often search for what age autism screening is recommended because they want to compare their child’s visit history with standard milestone care.
If a recommended screening window was missed, it is still worth discussing at the next appointment. Your child’s clinician can advise on the best next step based on age and current concerns.
A normal screening result does not mean you should ignore ongoing concerns. If something about your child’s communication, social interaction, or behavior worries you, bring it up directly with your clinician.
Autism screening is commonly recommended at 18 months and 24 months during routine well-child visits. These are widely recognized toddler milestone visits for autism-specific screening.
No. Autism screening is often recommended routinely at 18 months and 24 months, even if no concerns have been raised. If concerns do come up at any age, screening or further developmental review may also be discussed outside those visits.
If your child missed autism screening at 18 months, ask about it at the next well visit. Your child’s clinician can review whether screening should be completed now and whether any additional developmental follow-up is appropriate.
Yes. Autism screening at 24 months is commonly recommended even if screening was completed at 18 months. Development changes quickly in the toddler years, and the later milestone can provide additional useful information.
You can check your child’s visit notes, after-visit summary, or patient portal, or call the pediatric office and ask whether autism screening was completed at the 18-month or 24-month visit.
Answer a few questions about your toddler’s age and whether screening happened at 18 months or 24 months. We will help you understand where you are in the milestone schedule and what to discuss next with your child’s clinician.
