Knowing typical developmental milestones — and the ‘red flags’ that may warrant a closer look — helps you advocate for your child early.
Milestones and possible red flags
By around 12 months, many children babble, use gestures, and respond to their name. By 18 months, many use several words and point to share interest. By 24 months, many combine two words and engage in simple pretend play. Possible red flags include no babbling or gestures by 12 months, no words by 16 months, no two-word phrases by 24 months, or any loss of skills at any age. Children vary, so these are guides, not verdicts.
Trust the pattern, and act
Milestones are general guidance, not a diagnosis. If your child is missing several milestones or losing skills, talk to your pediatrician and consider an evaluation — NJ Early Intervention serves children under three. Early support makes a real difference. See evaluation resources by county.

What are autism red flags by age?
Possible red flags include no babbling or gestures by 12 months, no words by 16 months, no two-word phrases by 24 months, or any loss of previously gained skills. These warrant a conversation with your pediatrician.
My child is a little behind. Is that autism?
Not necessarily — children develop at different rates. But missing several milestones or losing skills is a reason to seek a developmental evaluation rather than wait.
