Key "Red Flag" Milestones (Do Not Miss)

AgeRed Flag if NOT achieved
2 monthsNo social smile, does not respond to sounds
6 monthsNo babbling, no reaching, no head control
12 monthsNo single words, no pointing, no waving
18 monthsFewer than 10 words, not walking
24 monthsNo 2-word phrases, no pretend play
3 yearsSpeech not understandable to strangers, no 2-word sentences
5 yearsCannot follow 3-step commands, no intelligible speech

Notes:
  • Milestones represent the age by which most (75-90%) children achieve the skill.
  • Gross motor includes balance, locomotion, and posture.
  • Fine motor includes hand-eye coordination, manipulation, and self-care.
  • Developmental screening is formally recommended at 9, 18, and 30 months per AAP guidelines.
  • Any regression of previously acquired milestones at any age warrants urgent evaluation.
