And a third mom, Carolyn Risoly, points out the irony in the outrage that breast-feeding moms sometimes arose.
"It's a very natural thing, and it's too bad people aren't comfortable with it," Risoly says.
Gillette's case adds another chapter to the debate that pits the rights of nursing mothers against notions of propriety.
Linda Blum, an associate professor of sociology and women's studies at the University of New Hampshire and author of "At the Breast," tells ABC News that some people see breast-feeding as improper, even though researchers have established that nursing delivers long-term health benefits to infants and mothers.
"It seems perverse to some," Blum says. "Because we have made breasts into sexual objects, we don't want to see women breast-feeding their children, although we keep saying 'breast is best.' We want breast-feeding to be out of sight."
