Why do other mom's put down moms who breastfeed in public? Why do other mom's put down other mom's because they DON'T breastfeed? I will never understand. I will never judge another mother's parenting style, because we all have our own style. We all have different backgrounds, cultures, and beliefs. Giving feedback is one thing, but talking shit is another.
