Developmental Health Watch

The developmental milestones give you a general idea of the changes you can expect as your child gets older, but don't be alarmed if her development takes a slightly different course. Each child develops at his/her own pace.
Do consult your pediatrician, however, if your child displays any of the following signs of possible developmental delay for this age range.

  • Frequent falling and difficulty with stairs
  • Persistent drooling or very unclear speech
  • Inability to build a tower of more than four blocks
  • Difficulty manipulating small objects
  • Inability to copy a circle by age 3
  • Inability to communicate in short phrases
  • No involvement in "pretend" play
  • Failure to understand simple instructions
  • Little interest in other children
  • Extreme difficulty separating from mother
