Colic and fussing in infancy, and sensory processing at 3 to 8 years of age

The purpose of this follow-up study was to examine whether a group of 28 clinic-referred infants with colic, excessive crying, or both at 4 to 12 weeks demonstrated sensory processing, coping, and behavioral/attention regulation difficulties at 3 to 8 years of age. Seventy-five percent of the sample demonstrated atypical behavioral responses to sensory experiences. Hours of fussing during infancy significantly correlated with inattention, emotional reactivity, touch processing, environmental coping, and externalizing behavior at 3 to 8 years, but not hours of crying. The most striking result was that children with more hours of early fussing showed less efficient sensory processing, poorer coping with the environment, and more attention/hyperactivity problems compared to those with less hours of fussing. Results suggest that hours of fussing rather than crying could be an early marker for infants at risk.
