Can men breastfeed and how?

Suckling. Men can not produce milk with which to breastfeed infants. However, infants often suckle their father's nipples in the Aka Pygmy tribe in central Africa. The Aka fathers "are within reach of their infants 47% of the time". This was studied by an American anthropologist named Professor Barry Hewlett. REF:
Be close to baby. One needs breast tissue to breastfeed and men do not have breast tissue. A sex change operation may give a former woman a manly appearance, but allow some milk production. Small amounts of milk production can be a medication side effect or a sign of a health problem. Dad's can hold their babies close and support breastfeeding moms in many positive ways.
