All children grow and develop at their own pace, but there are common milestones—like walking, talking, and social interaction—that typically happen within certain age ranges. Speech, language, and social skills are key indicators of development. Communication isn’t just about words; it also includes understanding meaning, responding to others, and building relationships.

In the early years, you may notice:

• By age 2: Using and understanding simple words (e.g., “mommy,” “ball”), recognizing body parts, linking words to activities (like “lunch” or “bedtime”), and using gestures such as pointing or shaking their head
• Between ages 2–3: Showing interest in other children, beginning to play alongside or with others, and starting to understand sharing and turn-taking

If your child is not meeting some of these milestones, it doesn’t necessarily mean they are autistic—but it may indicate they could benefit from extra support. Recognizing these differences early can help you find the right tools, strategies, or professional guidance to support their development.
