Things to try now

What to do now

  • 1Download and use the CDC Milestone Tracker app to monitor your child's development
  • 2Engage your child in simple 'serve and return' interactions by responding to their babbles and gestures
  • 3Schedule a discussion with your child's healthcare provider if you notice multiple missed milestones

What to say

  • I've noticed that your child isn't using as many words as expected for their age; let's talk about this with the doctor.
  • When you babble or point, I want to make sure I always respond so you know I'm listening.
  • It's okay if your child is developing at their own pace, but let's keep track together to support them.

What to practice consistently

  • Daily reading and talking to your child to build language skills
  • Encouraging play that involves social interaction and pretend scenarios
  • Consistently responding to your child's communication attempts to strengthen brain development

What to avoid

  • Comparing your child too strictly to other children’s development timelines
  • Ignoring repeated missed milestones or dismissing concerns without evaluation
  • Overloading the child with activities without responsive interaction

These are common approaches mentioned in sources and by parents. They are informational, not prescriptive.

What this usually involves

  • Tracking developmental milestones in language, motor skills, social-emotional, and cognitive areas
  • Using milestone checklists or apps like the CDC Milestone Tracker
  • Observing patterns rather than isolated missed milestones
  • Responsive caregiving practices such as promptly responding to a child's cues ('serve and return')
  • Consulting healthcare providers for professional evaluation if delays are suspected
  • Accessing early intervention services when recommended
