Besides preaching the gospel to him and the things of God in general, the most loving thing a woman can do for a husband is to nurse him. I feel this way because it’s not something physically necessary. Sure, men feel loved when their wives give them plenty of sexual action but sexual intercourse is very necessary for both spouses, and not only for procreative reasons. But a man does not need to drink his wife’s breastmilk. This is precisely why I think husband breastfeeding is the second most loving thing a woman can do for her man.
