Information on sample sizes was based on correspondence with the author. The authors report findings in the manuscript that are ineligible for review because they do not examine the impact of the intervention on an eligible outcome (for example, descriptions of infant fusses and feeds and descriptions of soothing strategies).
| Study participants | Study participants were mother and infant dyads recruited after delivery in one Pennsylvania hospital. To be eligible, dyads had to include full-term, singleton births, with infants of normal birth weight. Mothers were English-speaking, primiparous, and at least 20 years old. A total of 291 dyads were randomly assigned to either the Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) intervention (145 dyads) or a comparison intervention (146 dyads); 157 of the dyads were included in the analyses in this manuscript (81 in the intervention group and 76 in the comparison group). Mother–infant dyads were randomly assigned to the INSIGHT intervention or the comparison intervention two weeks after birth. Outcomes were measured when children were 3 weeks and 8 weeks old. In the study, 89 percent of mothers were White, 7 percent were Black, 2 percent were Asian, and 2 percent reported another race. Most mothers (62 percent) had annual household incomes between $25,000 and $99,000; 10 percent had annual household incomes below $25,000. Ninety percent of mothers were college educated. |

| Setting | The study took place in Hershey, Pennsylvania. |
| Intervention services | INSIGHT consisted of home visits conducted when infants were 3 to 4, 16, 28, and 40 weeks old, followed by annual clinic-based visits at 1, 2, and 3 years old. The curriculum taught parents to respond promptly and in developmentally appropriate ways to infant cues across four behavioral states (drowsy, sleepy, fussy, and alert/calm). Research nurses provided parents with developmentally appropriate sleep guidance during each visit. The guidance addressed bedtime routines, sleep location, and night waking. During and between visits, caregivers were provided with information and resources on responsive feeding, lactation support, soothing practices, and home safety (including crib safety and choking hazards). When infants were 2 weeks old, participants received a mailed packet with information on infant feeding. |
| Comparison conditions | Families assigned to the comparison condition were not eligible to receive intervention services through the INSIGHT program. However, these families received a similar number of home visits as the INSIGHT group (when infants were 3 to 4, 16, 28, and 40 weeks old) and annual clinic-based visits at 1, 2, and 3 years old. The home visits focused solely on home safety topics, including crib safety. When infants were 2 weeks old, participants received a mailed packet with information on infant feeding. |
