[영문]Using data from the Fragile Families and Child Wellbeing Study (N = 781), I examined how father visitation for children born outside of marriage is affected by subsequent maternal relationship formation, focusing on the timing, type, and stability of maternal relationships. Results showed that fathers were most likely to have not seen their child at all when mothers formed a new relationship early in the child's life, especially if the new relationship was coresidential and the partner engaged in activities with the child. Fathers who initially visited their child were more likely to stop visiting their child if an initially unpartnered mother became partnered. Frequency of visitation was not as strongly affected as whether visitation occurred at all.
