Breastfeeding is a common aspect of motherhood, but it can arouse an incredible amount of debate and downright furor. In November 2006, for instance, breastfeeding women at 19 different airports openly nursed to protest a woman being removed from an airline flight for refusing to conceal her breastfeeding 1-year-old with a blanket. TIME magazine similarly stoked a widespread breastfeeding controversy when it featured a 3-year-old boy suckling from his 26-year-old mother on a May 2012 cover. Somehow, this natural maternal act has, along with plenty of other parenting practices, become entangled with bickering and disputes over the best way to raise children. But breastfeeding disagreements are but a drop in the bucket compared to the unconventional child rearing tacks the parents featured in this gallery have taken. (Jeff Topping/Getty Images)
