I breastfed my older daughter until she was 26 months. My husband didn't have an issue with it because she is not his daughter, and by the time he was in the picture she was down to nursing at nap and bed time.
We now have a month old daughter together. We went out to eat and the baby got hungry so I nursed her. He looked at me in utter disgust and told me that the truck was right out front. We didn't have a discussion before Baby O was born , I just assumed that he knew I would feed the babe when and where she was hungry. I can deal with people outside of my life not being supportive; chalk it up to ignorance, offer my opinion, and move on. When it is my family I am beyond ideas. I explained how I felt and he replied that he thought it was gross and inappropriate "for my tit to be out in public".
We have been friends since before my older daughter was born and he knows that breastfeeding has always been important to me.
Ideally he would come to be a lactivist but mostly I need help opening his eyes. He sees breasts as purely sexual and I don't know how to change his viewpoint, the lactation and baby suckling hasn't done it.
