Grow2Gether Pilot Study

This novel intervention, delivered to mothers primarily through private Facebook groups,
will promote behavior change through peer and self-modeling photo/video activities.

In this study, investigators will implement the intervention with small peer groups of 6-12
mothers, beginning during the 3rd trimester of pregnancy. Investigators will assess
feasibility and acceptability of the intervention, and explore its impact on outcomes,
particularly behaviors associated with healthy growth.
