Columbiana Centre in South Carolina provide nursing moms in that area with a dedicated mothers room to comfortably express breastmilk for their infants.

"The first nursing lounge I was fortunate to discover is at Columbiana Centre. Located off the food court is a hallway leading to regular restrooms, family restrooms, a changing area, and a room that you can – hallelujah! – LOCK when nursing. With dimmed lighting, it’s the perfect place to calm down the likes of a hungry baby."

Note: South Carolina is a breastfeeding friendly state, and legally protects a mother's right to breastfeed in public. So if the weathers fine and you're comfortable in public places, you can breastfeed in SC where you want.
