Breast Feeding

Male Infant Milk Production???



My month old SON has developed a lump in his chest. It is situated behind his nipple and when squeezed (very , very gently) it leaks milk. He is breast-fed only. Can you please explain this to me.


During late pregnancy maternal hormone levels are very high, to prepare YOUR breast for breastfeeding. These high hormone levels are enough to sometimes cause breast engorgement and milk production in a baby (male or female). This appears by the third day of life and is gone by the second week of life. Since your son is a month old, you should have him see his health care provider for an evaluation.
