Junk science of the day – nannies make men into adulterers. The theory goes that from a young age, they learn that it takes multiple women (mom & the nanny) to fill their needs.

Having two maternal objects, says Friedman, “creates a division in [the boy's] mind between the woman he knows to be his natural mother and the woman with whom he has a real hands-on relationship: the woman who bathes him and takes him to the park, and with whom he feels completely at one.” This dual-woman life, one for family and one for catering to his every need, might become a set pattern in his mind, so that when he grows up and feels like his needs are not being met, he strays beyond the home.
