Summary

About 11% of new mothers experience postpartum depression, which can affect their baby's growth and development. This study tests whether treating mothers with blue light therapy improves their infants' development and growth during the first year of life. Researchers will compare babies of mothers who received blue light, a control light, or no depression, tracking milestones and physical growth.
