It has generally been assumed that lower socioeconomic status teenage parents are atypical in their expectations about child development compared to other parental groups. However there is little information available concerning the expectations of middle class parents. Middle class nonparent teenagers (N=50) and two parental groups (participants in Lamaze prenatal development classes (N=19) vs. those who had not participated in Lamaze classes (N=26) were assessed on their beliefs concerning developmental milestones in early childhood. Results indicated that the teenagers' mean scores were more realistic than the parental groups in several areas (e.g., motor development). However, a closer examination of error scores (absolute deviation from norm) revealed that the teenagers made statistically significantly greater errors while the parental groups (especially the Lamaze subjects) were closer to the norms, but still precocious in their expectations. The results may be a result of the "Proud Parent Syndrome," a phenomenon identified in previous research that finds parents, after their child's birth, concluding that their child is developmentally advanced compared to a normal child.
