My husband was and is all for me nursing but he can't stand me nursing in public. My dad just visited from out of state. He hated the fact that I nursed our 11 month old in front of my dad. He sat he wants to try again for a girl but.....If we are out in public I either have to use a cover up, go out to the car, OR take the little one and sit on a public toilet and nurse him/her. If I can't respect his feeling in the matter then there is no sense in us having another child. Even in my own home if somebody stops by I have to go hide in the nursery to nurse the baby.
For your situation, your husband should be more understandable toward you when you are nursing your baby. I have an idea, but I don't know if your husband is up for it. It would give him a better idea of nursing in public during the summer time. Have him feed baby with the blanket cover like he's breastfeeding her/him. He will see how much hard and too hot for you to use the blanket to cover up when you're feeding him/her. He may gain a new respect for you. Good luck!!!!
