The study team will perform a prospective, longitudinal, interventional, randomized control trial by recruiting 300 WIC families during the first 1,000 days of life (pregnancy through infant age 2 months) at consecutive Women, Infants, and Children (WIC) visits to test two interventions compared to a control group. The study team will implement a mobile-based messaging intervention allocate participants to one of 3 arms for a 1 month period: 1) negative message frames, 2) positive message frames, and 3) attention control.
