What to do now
- 1Use simple two-step instructions during daily routines, e.g., 'Please pick up your toy and bring it here.'
- 2Engage in pretend play with your child using toys or household objects.
- 3Talk and sing to your child throughout the day to build language skills.
What to say
- “I love hearing you say new words! Can you tell me what this is?”
- “Let's play a game where we pretend this cup is a hat!”
- “You're doing a great job following directions like 'put your shoes away.'”
What to practice consistently
- Consistent 'serve and return' interactions—responding to your child's sounds and gestures.
- Reading books together daily to encourage language and cognitive skills.
- Encouraging social interactions with other children to build cooperative play.
What to avoid
- Comparing your child's progress rigidly to others.
- Ignoring repeated delays across multiple developmental areas.
- Overloading the child with too many instructions or activities at once.
These are common approaches mentioned in sources and by parents. They are informational, not prescriptive.
What this usually involves
- Language milestones: saying first words by 12 months, 50 words by 2 years, simple stories by 4 years
- Motor skills: pulling to stand by 12 months, walking, running, and climbing by toddler years
- Cognitive skills: following two-step instructions by age 2, engaging in pretend play
- Social-emotional: showing preferences for people, playing cooperatively by age 4
- Responsive caregiving: adults promptly responding to child’s cues to build brain connections
- Tracking milestones using tools like the CDC Milestone Tracker app

'Serve and return' is a responsive caregiving practice where adults promptly and warmly respond to a child's vocalizations, gestures, or expressions to build brain connections.
If your toddler is not using any words by 18 months or shows little progress in language skills by age 2, it is advisable to consult a healthcare professional.
