Major motor skills

DevelopmentAn 18-month-old infant walks unaided, bends down to pick up objects without overbalancing, and is starting to climb.


Fine motor skills

Children of this age can drink unaided; feed themselves with a spoon; shows hand preference (e.g. left or right hand); can scribble with a pencil; and enjoys picture books, turning several pages at once. If demonstrated, they should be able to build a tower of three cubes.


Language

Children will often repeat words and jabber loudly. While they should be using 6–20 recognisable words, they will understand many more. They should be able to show their own or a doll’s hair, eyes, nose, shoes, et cetera on request.


Vision and hearing

Children should demonstrate everyday visual competence for near and far.


Social achievements and play

Children will often imitate activities and attempt to sing. The caregiver will report they are very demanding of attention and dislike being left behind. They begin to indicate toilet needs and begin to copy domestic activities.


When to be concerned

Tell your doctor if an 18-month-old child:

  • Does not show attachment to caregivers or preference for familiar people;
  • Is not walking;
  • Regularly appears not to listen when being talked to; or
  • Is not beginning to use any meaningful words.
