I think it's a roundabout way of saying that women who are earning money in the workforce are generally more independent and self-sufficient, so less likely to be abused by their husbands.

Providing breastfeeding locations in a workplace means that the mother can remain in paid employment longer, and it also means that the infant isn't left with a careless/hostile nanny at home.

Reading between the lines, are we supposed to get the impression that there is an amount of violence against infants coming from their nannies? Or is it just that nannies aren't providing the proper care (such as nutritious food, stimulating playtime etc) - hence the need to advise parents about hiring them?
