This is a well-worn trope, however, I suspect you are aware of that fact. Women who are too outspoken are regularly called nagging, emasculating, etc. Since in this case, IT IS in fact a woman, who seemed to be trying to act in the best interest of the family, since Dad seemed unable to consume responsible, that came off as very much a “nagging wife” trope.
But we don’t know that… the evidence we DO have, is that he had shown himself to be irresponsible in his consumption habits, and I’d suggest his later actions of just hiding his gummy stash bears that out.
Or maybe he’s just irresponsible, and she’s doing her best to keep the family safe from his bad choices… 
Again, given the evidence before us, this seems the most likely scenario.
