This study aims to describe the ways in which mothers of twins organize their childcare activities during the first year after a twin birth and to determine what factors might affect these mothering practices. The mother's physical and psychological state, support and help from the father and others in the surroundings, and the type of twinship were among the factors studied. Data on the organization of feeding, sleeping and waking routines were gathered from 51 families. A correspondence analysis and a cluster analysis showed that twin mothering practices can be described along two dimensions: individualized care vs collective care, and level of organization of daily routines. The mother's state of fatigue only partially accounts for the different types of maternal behavior. Likewise, the presence of several caregivers does not lead to greater individualization in care routines. Nor does there seem to be a clear link between the type of maternal behaviour and the type of twinship. The discussion deals with the mother's emotional investment, her personal capacity for adjusting to the "triadic motherhood' process, and the nature of the father's involvement in that process. Another consideration is the impact of the type of childcare pattern on twin development.

Prenatal exposure to per- and polyfluoroalkyl substances (PFASs) has been linked to adverse fetal growth and development. However, most evidence was generated based on the singleton pregnancy studies, whereas potential impact on twin fetuses remains largely unknown. This study aimed to explore the associations of prenatal PFAS exposure with the growth and developmental differences within twin pairs by investigating 162 twin newborns and their mothers and determining 19 PFASs in maternal serum during the first, second, and third trimesters and cord serum of twins.

Objective: This study examined the potential link between maternal pre-pregnancy body mass index (PPBMI) with neonatal outcomes in twin pregnancies.
Methods: This retrospective analysis records of 1,270 women with twin pregnancies, delivered at the Fujian Maternity and Child Health Hospital between 2019 and 2021, were retrospectively analysed. Women were diagnosed as underweight, normal BMI, and overweight/obese according to their PPBMI.

The attachment relationship constitutes the first emotionally significant affective bond, usually between the infant and the mother, serving as a model for subsequent relationships. It is considered a vital component of social and emotional development in the early years and an important early indicator of infant mental health. In twins, the attachment process may exhibit unique characteristics, influenced by the dual parenting dynamic and the individual needs of each baby.

Twin studies have suggested extremely high estimates of heritability for adolescent executive function, with no substantial contributions from shared environment. However, developmental psychology research has found significant correlations between executive function outcomes and elements of the environment that would be shared in twins. It is unclear whether these seemingly contradictory findings are best explained by genetic confounding in developmental studies or limitations in twin studies, which can potentially underestimate shared environment.

Objectives: Hemophilia A (HA) is an X-linked recessive inherited bleeding disorder that typically affects men. Women are usually asymptomatic carriers, and rarely presenting with severe or moderately severe phenotype. This study aims to describe a case of a 17-year-old girl with moderate HA, investigating the mechanisms of her condition and the genetic basis within her family.
