Using questionnaires distributed to mothers, the characteristics of early development in twinship were investigated. Results indicated twinship to be an at-risk situation with neonatal complications and within-pair differences in the attainment of developmental milestones. The implications of these differences raise questions about the accuracy of the equal environments hypothesis.
