4th Trimester is a nonprofit transforming the postpartum experience for mothers and birthing people in California and along the U.S.–Mexico border. 4th Trimester provides practical support, emotional care, economic assistance, and advocacy, ensuring no parent navigates the fourth trimester alone.

Through our collaboration with 4th Trimester, we’re proud to support their mission of improving postpartum care for new mothers and birthing people. Founded by mothers who experienced the challenges of postpartum firsthand, 4th Trimester began by providing recovery essentials, diapers, and emotional support to families in need. Since then, they’ve expanded their work to include mental health resources, economic assistance, and advocacy for underserved communities, including low-income, immigrant, asylum-seeking, and disaster-impacted families. Their name reflects the belief that the postpartum period deserves the same care and attention as every other stage of pregnancy.
