what's this supposed to mean?

Mommy
So I posted on good ole FB that we are expecting our third son. Someone commented "at least you already know how to handle men...." don't know what that means? "At least you already know how to handle men" hmmmmm want to keep pregnancy hormones in check and not be a butthole responding but what do they mean by that comment?? I guess it's just kinda extra awkward because it's my cousins wife and she never comments unless it's a snarky remark
