Abrams Road WIC in City of Dallas has in place a dedicated lactation room open to all moms of the general public. Once you come in simply ask someone on staff to direct you to it if you need help getting in. The room comes ready with a door you can lock for privacy while pumping or nursing, there's an otlet to connect your powered breast pump, there's comfy seating, and a changing table.
