How to Recognize Early Signs of Autism in Your Toddler

Learn the key early signs of autism in toddlers to help you understand your child's development and when to seek professional guidance.

  1. Social Communication Differences. Watch for how your toddler connects with others. They may have limited eye contact, not respond when you call their name, or seem uninterested in playing simple games like peek-a-boo. You might notice they don't point to show you things they find interesting, or they may not look where you're pointing. Some toddlers may not wave goodbye or use gestures to communicate their needs.
  2. Speech and Language Patterns. Pay attention to how your child's language develops. Some toddlers may not babble much as babies or may lose words they previously used. Others might repeat phrases from TV shows or books without using them to communicate. You may notice they have trouble starting conversations or taking turns in simple back-and-forth exchanges. Some children may speak in an unusual tone or rhythm.
  3. Play and Interest Differences. Observe how your toddler plays and what captures their attention. They might line up toys instead of playing with them imaginatively, or become very focused on specific parts of objects like spinning wheels. Some children develop intense interests in particular topics and may talk about them constantly. You might notice they prefer to play alone or have difficulty engaging in pretend play.
  4. Repetitive Behaviors and Routines. Look for repeated movements or behaviors like hand flapping, rocking, or spinning objects. Your toddler might insist on sameness in daily routines and become upset by small changes. They may repeat words or phrases over and over, or need to follow very specific patterns in how they do things like getting dressed or eating meals.
  5. Sensory Sensitivities. Notice how your child responds to different sensations. They might be bothered by certain textures, sounds, or lights, or they may seek out intense sensory experiences like jumping or spinning. Some toddlers may not notice when someone enters the room, while others might be overwhelmed by normal household sounds.
