This is some flagrant anti-breastfeeding stupidity. Beer is -— I kid you not-— like a milk-friendly nutrient smoothie. Keeps mom relaxed and hydrated, contains B vitamins and such for baby.
If I were in that bar I would have verbally defended that woman from the arresting officers.
My mother raised 10 children including 7 girls who all had children and breast fed. When my wife and sisters had children (or grandchildren) Mom always recommended a beer to stimulate breast milk. It worked every time especially if they were having trouble initially getting flow. Mom also recommended vanilla ice cream, but I’m not sure if it actually helped or she just loved vanilla ice cream.
I heard a news report on the radio that said she was offering sex for more beer.
