It seems like a safe guess that very few of the moms complaining about their partners on r/parenting are also married to the dads who are posting on r/daddit.
It's like how /r/steak is just dudes posting steak pictures, and there is some new cooking sub where it's just women posting food pictures and complaining about their significant others. Women be complaining.

If you are referring to /r/girldinnerdiaries, that is not a cooking sub, nor is it intended to be. The whole point is pairing a photo of dinner with the situation and mood of the photographer.
It's right there in the name: Girl Dinner Diaries.
I'm not sure how serious you are about the dismissive "women be complaining" comment. A big part of your perception may be that women have more to 'complain' about; society is measurably unfair for women. Another part could be that when women voice their struggles it is called "complaining," and when men voice their struggles they are "being serious." Also, men get shot down for showing vulnerability and seeking support, so their struggles are internal. And this isn't always good for mental health.
My comment was descriptive, not normative. I’m not ascribing moral valence to it, just stating what’s happening and speculating why. For example, men probably complain less because men get shot down for showing vulnerability in public settings like online forums. Women probably complain more in public because they get sympathy. Whether one is good, or one is more mentally healthy, I don’t think either is healthier or unhealthier, but I don’t particularly care.
On the other hand, /r/parenting was full of moms desperate because their partners didn't to their part.
It really paints a picture, if you think about it.
