Awesome update! Men can be such babies sometimes. He probably panicked last minute when he realized he was going to have sole responsibility and curtailed freedom for a couple of weeks. Good for you for standing up for yourself. Glad he stepped up.
I don't feel this is a fair generalization. Yes, the OP's husband was less than supportive and cooperative, but that doesn't mean that all men are "babies."
No-one said all men are babies.
No, but "men can be such babies" implies that "being a baby" is related to gender, which it's not.
Actually, it was, "men can be such babies sometimes".
The word sometimes doesn't change a thing. The fact that the subject of the sentence is "men" suggests that gender has something to do with being a baby. And it doesn't. If the sentence read "people can be such babies sometimes," that would solve the problem.
