Description of the Symptom

Often, parents or caregivers present to the clinic with concerns that their child is not performing skills that other children his or her age are, or that perhaps a sibling did at the same age. The child may not be rolling, crawling, sitting, reaching, standing, or walking at the age that most children are able to perform those skills. This chapter discusses many of the causes that may contribute to delayed mobility, failure to thrive, and psychomotor delay.

Special Concerns

  • Neurological signs, such as rapid changes or loss of consciousness, sudden weakness/paralysis, sudden or new onset of uncontrolled seizures1

  • Rapid decline in function over short period of time, especially if associated with vomiting or lethargy

  • Evidence of abuse/neglect
