Mothers' representations of their 13-month-old twins and child-raising attitudes

The purpose of this study was to describe maternal representations of the twin sibling relationship and of the children's differences and similarities. Mothers' mental representations were also analyzed with regard to two aspects of their child-raising attitudes: individualization of childcare routines, and the question of differentiation by “external signs of twinship” (dress, toys, and first names). Data from interviews with 44 mothers of twins conducted 13 months after the birth were analyzed in terms of 8 categories—complicity, rivalry/jealousy, agonistic relations, dominance, imitation, physical appearance, development, and personality. A multiple correspondence analysis of the data pointed out that the first dimension describing the mothers' representations concerns the contrast between the “unalike” representation of dizygotic twins and the “alike” representation of monozygotic twins. The second dimension corresponds to the casual, twinship-minimizing representations generated by the twin condition. Two other dimensions express the issues of aggression and dominance. The relationship between the child-raising behavior of the mothers and their representations of the twin couple turned out to be more complex than expected. The results are discussed in terms of the specificity of the psychological issues facing mothers of twins. Defense mechanisms used by some mothers to cope with the exceptional nature of the twin phenomenon are also suggested. © 1998 Michigan Association for Infant Mental Health
