"Men are absolutely terrible at breastfeeding, but they're very very good at baby calming! The swaddling is like an engineering task, and the jiggling, women are a little bit more timid about doing that, men are a little bit more willing to follow the directions," Dr. Karp explains, of his famous approach to baby calming, known as the 5 S's. He encourages dads to step up when it comes to baby calming, explaining, "that really supports the mom in her feeding and other care for the baby." It also helps dads to strengthen their bond with a new baby, especially if the mother is exclusively breastfeeding.
