Women who had positive relationships with their own mothers reported good attachments to their first child before and after birth.

Aim: Bowlby's attachment intergenerational transmission theory suggests that a woman's attachment to her parents, particularly her mother, plays an important role in her future parenting. We studied whether there was any association between pregnant women's attachment to their baby before and after birth and their relationships with their mothers.

Methods: A longitudinal study was carried out in 2015 on 201 first-time mothers recruited in the maternity ward of the level two Misericordia e Dolce Hospital in Prato, Italy. At 32 weeks of pregnancy, the women filled in the Parental Bonding Instrument and the Prenatal Attachment Inventory and their spontaneous attachment behaviour towards their newborn infants were observed in the nursery during the first two days after childbirth.

Results: Having a good relationship with their own mothers was a positive predictor for the women's prenatal attachment to their baby and caregiving and attachment behaviour to their newborn infants. In addition, the mothers' prenatal attachment positively predicted their behavioural attachment pattern after birth.

Conclusion: We found that women who had positive relationships with their own mothers also had positive attachments to their unborn babies and in the period immediately after birth. Our findings supported Bowlby's attachment intergenerational transmission theory.
