Weekly content for the intervention and control groups.

Advisory Board recommendations	Resulting modification to the Healthy Beginnings interventions
Mechanism for social support	Advisory Group participants wanted a sense of community within the programs. Virtual support groups were created through Facebook. Separate and private groups were created for intervention and usual care groups.
Video-based content	Short, 2 to 4 min videos were professionally produced to deliver intervention lessons to participants.
Relatable recipes	Research dieticians developed 24 recipes that incorporate WICa-eligible foods. Preparation of these recipes are demonstrated in full length (n=10) and fast forward videos (n=14).
Exercises for pregnant women	8 coach-led group exercise classes were produced along with 24 exercise of the week videos. All exercise materials are suitable for women to perform safely throughout pregnancy.
Gamification program to incentivize mothers	Mothers wanted to earn points for intervention adherence. The Mommy Market was developed so that participants in the intervention could earn points from demonstrating an understanding of intervention content and redeem points for pregnancy and infant-related products at the Mommy Market.
