Seriously the worst most awful thing ever is teaching our children what's normal and natural!!! That bottles aren't the ONLY option. My sons pretend to breastfeed toys and pump breastmilk for each other. What the hell is WRONG with that.
My boys know that some babies breastfeed, some get pumped milk, and some get formula but the best option in breastfeeding.
Seriously grow up! Breasts can be both sexual and for nutrition. Doesn't mean breastfeeding is sexual!
