Fathers cannot breastfeed. They still decide whether it works.

Ask most Nigerians who is responsible for breastfeeding and the answer is immediate: the mother. Ask who determines whether it succeeds, and the honest answer is considerably more crowded.

A new mother in the first six weeks is exhausted, often recovering from surgery or tearing, feeding eight to twelve times in twenty-four hours, and receiving advice from every adult within range. Whether she continues exclusive breastfeeding through that period depends far less on what she knows than on what her household does. Research from Nigeria has been consistent that family attitudes, particularly those of partners and grandmothers, are among the strongest predictors of whether exclusive breastfeeding survives past the early weeks.

That is a hopeful finding, because household behaviour is cheaper to change than health system capacity.

Start with the fear that goes unspoken. In some families, breastfeeding is quietly resisted because of a belief that the mother’s closeness to the baby displaces the father, and that the bond between man and child suffers for it. It is worth saying plainly that there is no evidence for this. A father’s bond with his child is built through his own contact with that child: holding, soothing, bathing, carrying, being present at night. None of that is in competition with feeding. A father who wants closeness has an enormous amount available to him, and none of it requires the baby to be fed differently.

What actually helps is unglamorous.

Cook. A woman feeding a newborn around the clock frequently does not eat properly, not because food is unavailable but because she cannot get to it with one arm and no sleep. A plate she can reach with one hand is a direct intervention in milk supply.

Carry. Between feeds, take the baby. Not for five minutes as a favour, but as a matter of routine. A mother who gets two consecutive hours of sleep produces more milk than one who gets forty minutes at a time. Rest is not a luxury item in lactation. It is an input.

Fetch water. Put a covered cup where she sits to feed and refill it without being asked. Thirst arrives mid-feed, when she cannot get up.

Take the older children. The second and third baby are harder than the first, and the constraint is almost never the newborn.

And say something. This is the one men skip most often and it costs nothing. A woman who is fourteen days into cluster feeding, sore, and being told by three relatives that her milk is insufficient needs to hear from the person closest to her that she is doing well. That sentence has kept more breastfeeding relationships going than most educational materials.

Grandmothers occupy a different position and deserve a direct address. In many households, no decision about a newborn survives contact with the grandmother’s disapproval. That influence is usually treated by public health people as a problem to work around. It is more useful to treat it as the single most powerful asset available. A grandmother who encourages colostrum, who tells her daughter or daughter-in-law that the small yellow milk is the good milk, who says that water can wait until six months, will move a household in a way no campaign can. Her blessing outranks our graphics, and we know it.

None of this requires money, training, or a policy change. It requires the people around a nursing mother to decide that her feeding her baby is a household project rather than her private responsibility.
