"Mother's child" and "father's child" among twins. A longitudinal twin study from pregnancy to 21 years age, with special reference to development and psychiatric disorders.
TLDR
Mothers seem to develop a tighter affectionate bond towards their favourites than do fathers, thus inducing a good basic trust and faster language acquisition in childhood, but probably also transient non-specific neurotic symptoms in adolescence in face of the developmental task of entering autonomous adulthood.
