Here's what I sent:
I just noticed a news report stating that the city of Forest Park recently passed an ordinance that prohibits a mother from breastfeeding a child older than two years old in public. However, Georgia state law protects the right of the mother to nurse her baby, regardless of the age of the child. As you of course know, that state law would trump the municipal ordinance. I'd like to request that you check with the Attorney General's Office to make sure that your ordinance is not in conflict with state law. I'm attaching the text of the state law for your convenience.
Georgia Code - Health - Title 31, Section 31-1-9
The breast-feeding of a baby is an important and basic act of nurture which should be encouraged in the interests of maternal and child health. A mother may breast-feed her baby in any location where the mother and baby are otherwise authorized to be.
