Objective. To assess differences in family functioning or child-rearin
g attitudes within families with previously colicky infants and to ass
ess whether the children differed in their behavior, development, or f
requency of allergies. Study Design. A controlled, prospective study w
ith infants (3 months to 3 years of age) and their families. Participa
nts. Three hundred thirty-eight infants with and 866 infants without e
xhibited colic and their families. Methods. Questionnaires to mothers
and nurses regarding infantile colic (3 months of age); questionnaires
to mothers, fathers, and nurses regarding interactions within the fam
ily, parents' satisfaction with daily life, child caring, child behavi
or, and development (3 years old); the Denver Developmental Screening
Test (parents filled out at home during the whole 3 years of infant de
velopment); the Achenbach Behavior Checklist for 2-to 3-year-old child
ren (the 3-year visit at a well baby clinic). Results. The families of
previously colicky infants demonstrated more dissatisfaction with the
arrangements of daily family responsibilities and with the amount of
both leisure time and shared activities. The children in the colic gro
up had more sleeping problems and more frequent temper tantrums (at 3
years of age) than the control group. Conclusions. The families with c
olicky infants had more distress 3 years later. Families with colicky
infants should be provided practical support in improving daily family
functioning and child rearing. In addition, underlying problems in fa
mily relationships should be managed appropriately.
