Your Brilliant Baby in Week 12: Correlating Dads and Diapers

Baby’s Brain in Week 12

He may never make a peep about it, but by now, Dad might feel that Baby prefers Mom—and that may bum him out. When he holds Baby, she may squirm and look around for Mom. And when passed to Mom, Baby may quiet almost instantly.

The big secret? The only real preference that Baby has for Mommy is that she, if nursing, is Baby’s sole source for food, which she knows she needs to survive. Even when not nursing, a breastfeeding mom’s scent provides comfort as her child associates it with breast milk. (Remember those week 4 pacifier studies?) Ultimately, Baby may seem more relaxed with Mom over Dad because she knows, instinctively, that Mom equals food.

Yet other than nursing, dads are fully capable of all caregiving tasks: feeding from a bottle, burping, rocking, comforting, playing, and changing diapers. We now know that the messier the task he undertakes, the better Dad’s chances are of having Baby cozy up to him.

What the Research Shows

Researchers wanted to know the difference between the dads whose children readily turned to them and those who didn’t. They conducted a study that involved counting the diapers that the dads changed. For the daddies who took the time and got beyond the ick factor, changing diapers seemed to secure the child’s attachment to Dad as well as to Mom: The more diapers dads changed, the more babies turned to their fathers for comfort when distressed—even when mom was in the vicinity.
