Firstborns' behaviours were examined at different weeks of the mother's pregnancy. Their behaviours were compared to those of preschoolers whose mothers were not expecting. Eighty preschoolers participated: 20 from each trimester of the mother's pregnancy and 20 in a comparison group. At 16 and 20 weeks, first trimester firstborns had fewer difficulties with separation, insecurity, and dependency than at 12 weeks. At 24 and 28 weeks, second trimester firstborns were less dependent than at 20 weeks, and at 28 weeks less insecure than at 20 weeks. At 38 weeks, third trimester firstborns exhibited fewer separation and dependency behaviours than at 28 weeks. First and third trimester firstborns differed from the comparison group, but not in the expected direction. At 16 and 20 weeks, firstborns showed fewer separation problems than the comparison group. At 16 weeks, firstborn boys were less insecure than their counterparts, and at 38 weeks, firstborn boys had fewer separation problems and were less angry than comparison boys. It would appear a mother's second pregnancy does not appear to be particularly distressing for firstborns.
