Developmental Milestones - 18 months

Important Milestones: Your Baby By Eighteen Months
Milestone Checklist
How your child plays, learns, speaks, acts, and moves offers important clues about your child’s development. Developmental milestones are things most children can do by a certain age. Check the milestones your child has reached by the end of 18 months. Talk with your child’s doctor at every visit about the milestones your child has reached and what to expect next. What most babies do by this age:

  • Likes to hand things to others as play
  • May have temper tantrums
  • May be afraid of strangers
  • Shows affection to familiar people
  • Plays simple pretend, such as feeding a doll
  • May cling to caregivers in new situations
  • Points to show others something interesting
  • Explores alone but with parent close by
  • Says several single words
  • Says and shakes head “no”
  • Points to show someone what he wants
Cognitive (learning, thinking, problem-solving)

  • Points to get the attention of others
  • Shows interest in a doll or stuffed animal by pretending to feed
