Get clear, age-appropriate guidance on infant developmental screening milestones, including what to look for at 6, 9, and 12 months. If you’re wondering when to screen infant development or have questions about early social, communication, or motor differences, this page can help you take the next step with confidence.
Share what’s prompting your search, and we’ll help you understand which infant developmental screening milestones may be most relevant right now, what to watch for at your baby’s age, and how to think about next steps in a calm, informed way.
Developmental screening for babies is a structured way to check whether early skills are emerging as expected for age. It often looks at communication, social engagement, motor development, problem-solving, and everyday behaviors. Screening does not provide a diagnosis, but it can help identify whether a baby may benefit from closer monitoring, a conversation with a pediatrician, or a more complete evaluation.
Many parents search for an infant developmental screening checklist because they want to make sure development is on track. Screening can help organize what to look for by age without relying on guesswork.
If your baby seems to be missing milestones, showing less eye contact, fewer sounds, or different social responses than expected, screening can help clarify whether those concerns should be discussed further.
Pediatricians and caregivers may recommend screening during routine visits, especially around key milestone windows. This can be a helpful starting point for understanding what follow-up, if any, makes sense.
At 6 months, screening often considers early social engagement, response to sounds and faces, rolling or other motor progress, and whether a baby is beginning to show interest in interaction and play.
At 9 months, providers may look at babbling, back-and-forth interaction, sitting or mobility progress, response to name, and how a baby explores people and objects in their environment.
By 12 months, screening may focus on gestures, early communication, social connection, movement skills, and whether your baby is showing expected patterns of curiosity, imitation, and engagement.
Parents often ask when to screen infant development. Screening may happen during regular well-child visits, especially when milestone check-ins are expected, but it can also be helpful any time you have concerns. You do not need to wait for a major delay to ask questions. Early attention to developmental patterns can support earlier guidance, clearer monitoring, and more informed conversations with your child’s healthcare provider.
A baby developmental screening milestones review can show whether current skills seem broadly in line with what is typical for your baby’s age range.
An infant developmental screening questionnaire can highlight patterns in communication, social interaction, motor skills, or behavior that may deserve follow-up.
If concerns come up, screening can help you organize observations, track examples, and feel more prepared for a pediatric visit or referral discussion.
Some parents arrive here because they are wondering about infant autism developmental screening. In the first year, screening usually focuses on broad developmental patterns rather than a single condition alone. Differences in eye contact, social engagement, response to name, gestures, or communication may be worth discussing, but many behaviors can have more than one explanation. A thoughtful screening process helps place those observations in context and supports appropriate follow-up without jumping to conclusions.
Developmental screening is an early check of milestones and behaviors to see whether a baby may need closer monitoring or further evaluation. It does not diagnose autism or another developmental condition on its own.
Screening often happens during routine pediatric visits in the first year, including around 6, 9, and 12 months, but it can also be appropriate any time a parent or caregiver has concerns about development.
A checklist may include questions about social interaction, communication, motor skills, play, response to sounds or people, and whether your baby is meeting age-related developmental milestones.
In infancy, screening usually looks at overall development and early social-communication patterns rather than confirming autism by itself. If there are concerns, a pediatrician can help determine whether monitoring or a specialist referral is appropriate.
One milestone alone does not always mean there is a problem. Babies develop at different rates. What matters most is the overall pattern across skills and whether there are persistent concerns in communication, social engagement, movement, or behavior.
If you’re comparing milestones, wondering whether to screen now, or trying to make sense of early developmental differences, answer a few questions to get guidance tailored to your baby’s age and your concerns.
