Preterm infants exhibit a similar crying pattern to full-term infants, peaking around six weeks corrected age. This early crying peak appears to be a universal developmental feature in human infancy.

Area of Science:

  • Developmental Psychology
  • Neonatal Research
  • Infant Behavior

Background:

  • Healthy full-term infants typically experience a peak in crying during the first three months of life, often concentrated in the evening.
  • Understanding crying patterns in preterm infants is crucial for assessing their developmental trajectory and well-being.

Purpose of the Study:

  • To investigate if preterm infants display a similar crying pattern to full-term infants.
  • To describe the crying characteristics of preterm infants from 40 weeks gestational age to 24 weeks corrected age.

Main Methods:

  • Longitudinal description of crying patterns in 35 relatively healthy preterm infants (born 28-34 weeks gestational age).
  • Data collected from 40 weeks gestational age through 24 weeks corrected age.

Main Results:

  • Preterm infants cried significantly more after 40 weeks gestational age.
  • A peak in crying and evening clustering was observed at 6 weeks corrected age.
  • The age of peak crying was independent of gestational age, birth weight, and perinatal factors.

Conclusions:

  • The early-peak crying pattern is a robust maturational feature of early human development.
  • This crying pattern may be a universal characteristic across all human infants, regardless of gestational age at birth.
