This study examines why low‐income, unmarried parents who say that they plan to marry at the time their child is born do not follow through on their plans. We use data from a nationally representative birth cohort survey—the Fragile Families and Child Wellbeing Study (N =3,710)—combined with data from an embedded qualitative study—Time, Love, Cash, Caring, and Children (n =47)—to explore the reasons behind this apparent discrepancy. We find that some of the difference between parents’ expectations and behavior may be because of the overstatement of intentions at the time of the birth. Most of the discrepancy, however, results from parents’ perceived social and economic barriers to marriage. Specifically, unmarried parents have a long list of financial and relationship prerequisites they believe must be met in order for them to wed. Combined with other factors, these standards lead to an indeterminate delay in marriage.

The Hispanic paradox may extend to other non-Hispanic immigrants for breastfeeding behaviors, but may not be true for Hispanic mothers born in the United States. Low rates of breastfeeding for Hispanic American mothers indicate that they should not be overlooked by breastfeeding promotion programs.

Using data from the Fragile Families and Child Wellbeing Survey (N = 2,954), a birth cohort study, this work examines how gains in earnings and income are associated with marriage and subsequent childbearing for low‐income couples. Using change models, results indicate that positive changes in earnings, controlling for baseline levels of earnings, were associated with greater odds of marriage. Cohabiting couples who became poor were associated with a 37% decrease in marriage likelihood. Neither earnings nor income was affiliated with additional fertility. Results are consistent with the Financial Expectations and Family Formation theory, which posits that positive economic circumstances are necessary for marriage, but are not associated with subsequent childbearing.
