we go to work every day! wtf....

"to look after our twins BY HIMSELF all day, LIKE I NORMALLY DO". (sorry for the caps, I can't find a bold or italic option) That might be the clue that he doesn't normally help with the kids. I would also suggest that the fact that she had to issue it as a challenge, is that she was trying to prove that that work is more exhausting than it sounds on paper. Also she might just have put it down as an FML for a bit of a joke rather than being deadly serious that her husband can actually help. And your point about a woman being called a domestic goddess if she did what the husband did - that might actually be part of the problem. Generally speaking the purported image of motherhood is coping with ease with the children, the chores, the dinner. Rather than being honest that it's tough and you're not a failure if you find it difficult, and that message opens up both genders to being realist rather than men assuming the woman's got it under control and the woman not wanting to nag for help. Yes, people are becoming better at talking about the realities and I'm generalising and not everyone is like that, but there's still conversations to be had about the division of "unpaid work".

indeed. and then they say it's a different story when we need to do this every day. I wish we could!! we have to work for a boss everyday.... we man are always losing when it's about things like this

No one is minimizing what the husband did, let alone because he's a man. They're pointing out that it's a hard job, AND gets harder the longer you have to do it. And considering that the husband wouldn't have spent the last nine months pregnant, and have either squeezed two babies out or have been cut open to remove them- the latter of which can take months to fully heal, and up to a year and a half to fully recondition the muscles- and dealing with hormone changes that cause fatigue for months after pregnancy, yeah, biologically speaking, the husband DID have it easier. Especially only doing it for one day after an unknown period of leaving OP to do it by herself everyday, which leads to social isolation that has been proven to cause degeneration in physical and mental state. That the husband *can* do it, isn't the problem. The problem is that he can do it and hasn't been, which implies that he feels no sense of responsibility toward the household or the children.

For real, dude. So many strong feelings!

For doing the same thing that OP does on a day to day basis? Uh, no. It means that he needs to put in some more work around the house the other 364 days of the year.
