My sister in law works in a children's hospital and had to teach a 13 year old to breastfeed her baby with her 12 year old boyfriend watching. Considering I had only just helped her with breastfeeding it was a creepy and strange experience with her. Especially since the dad turned bright red and was embarassed when SIL mentioned the word breast. She snapped something to him along the lines of, "You liked them well enough when you got her pregnant so don't turn away. Your child needs to eat"
