When to Seek Evaluation

Contact your pediatrician if your child:

• Not walking by 18 months
• No words by 16 months; fewer than 50 words or no 2-word phrases by 24 months
• Loses previously acquired skills (regression)
• Doesn't respond to name, limited eye contact, no pointing or showing
• No pretend play by 24 months
• Persistent toe-walking, hand-flapping, unusual sensory reactions
• Asymmetrical movements, persistent fisting, hypotonia or hypertonia

Supporting Development

• Talk, read, sing daily—narrate life.
• Floor time: follow child's lead.
• Safe exploration; limit screens (<1 hour/day high-quality, co-viewed; AAP).
• Outdoor play, sensory experiences.
• Routines for meals, sleep, transitions.
• Positive discipline: redirect, name emotions, model regulation.

Early intervention (Part C / Early Start) is free, family-centered, and highly effective. Trust your instincts—you know your child best.
