Recognizing Signs of Developmental Delays That Require Evaluation

A structured overview of what credible sources and parent perspectives commonly say about this topic.

Quick answer

Developmental delays are identified when a child consistently misses key milestones in language, motor skills, cognition, or social interaction, such as not saying 50 words by age 2 or not engaging in pretend play. The CDC’s Milestone Tracker app is a useful tool for monitoring progress, and professional evaluation is advised if delays appear across multiple areas.

What to do now

  • 1Download and use the CDC Milestone Tracker app to monitor your child's development
  • 2Engage in daily 'serve and return' interactions by responding warmly to your child's sounds and gestures
  • 3Note any consistent delays in multiple areas and prepare to discuss these with your child's doctor

What to say

  • “It’s okay if you’re not doing everything yet; we’re working together to help you learn new skills.”

What to practice consistently

  • Regularly reading books and telling stories to your child
  • Encouraging pretend play and cooperative games with other children
  • Consistently responding to your child's communicative attempts with enthusiasm

What to avoid

  • Ignoring repeated delays across multiple developmental areas
  • Comparing your child harshly to peers or siblings
  • Delaying seeking professional advice when concerns persist
