Regressions include state dummies, main effects of eligibility criteria (worked before birth, single mother and no parent with a high school diploma) and controls for: race/ethnicity; education of mother and partner at 9 months; mother’s age at birth and its square; parents cohabiting; other family type; number of previous children; other child age 2 or under in household; other child age 3 or 4 in household; mother foreign born; mother’s primary language not English; urban/rural; mother’s family received welfare in childhood; education of mother’s parents; mother lived with biological parents until 16; pre-pregnancy BMI and alcohol consumption; desired number of children; number of challenging life events; child sex; multiple birth status; normal/low/verylow birth weight.
