Patting men on the back for simple tasks

I’ve been noticing this a lot lately- grown men in relationships being praised like little children when they do something to "help" around their own houses or take care of errand/task that needs to be done between both partners.

I can see this with some older men, who may have been raised that women "take care" of things and maybe moved straight from their mother’s house to their wife’s. But the guys I’m noticing it with now are in their early 30s. They’ve lived on their own for many years and are successful at work and education. But their partners praise them for successfully going to the grocery store or calling the plumber or folding towels. I’m pretty sure they had to do all those things when they lived on their own!

I don’t know where this comes from. Maybe TV and commercials and things like that where women always play the role of the mother to their husbands/boyfriends, asking them to do chores, rewarding them or punishing them, seeing them as children, etc (I’m sure you’ve seen commercials where women will say something like, "with three kids and a husband, my house gets pretty dirty). Maybe both parties in the relationship like to emphasize gender stereotypes and roles because it makes it all seem more "relationshipy"? It seems that when a couple moves in together or gets married, the women suddenly become much more "parental" overnight, while the men seem to regress. What do you all think about this?
