I cook today because my mother taught us to cook as kids. Obviously, cooking with a 5 year old is a bit of a burden, but as kids get older they are more helpful, and then you get extra, productive, and positive family time. And then later, older kids can often be convinced to cook the entire meal on their own if they get to choose the menu.

Barely relevant: neither I nor anyone I know instagrams their food. This may be a cultural artifact of your local population. Or of my local population.
