Just generally speaking, I think it's indicative of the underlying misogyny in our culture, which devalues 'women's work'. Ie, why would a man want to do that? it's why people get in a twist about lactation breaks, breastfeeding in public (do it in private, unless you're flashing your titties for someone's enjoyment!), the (non)rights of women in childbirth, and why men are often disadvantaged in the workplace if they try to take on a greater fathering role, or are even derided for it.

It's good to have potentially opened someone's eyes about alternate options. This is the way forward.
