lactivists

Nursing mother's protest grows
Organizers target Delta today
Raja Mishra, Boston Globe, 10/21/06

"Today, with the frantic Thanksgiving travel week underway, dozens of self-proclaimed 'lactivists' plan to suckle their infants in front of Delta ticketing counters around the nation, including at Logan International Airport."

"The American Academy of Pediatrics recommends that new mothers give only breast milk for the first six months of a child's life, and says there is no evidence of harm if breastfeeding continues into a child's third year."

I'd say by age three the child should be on solids.
