Due to the shutdown of preschools since March, obviously you have to keep your kids at home with you. 

Because nobody had a crystal ball (and nobody does still), it makes sense why, at first, many moms figured "OK I guess it'll be chaos for a few weeks at home, but then all the preschools will reopen so we can send our kids back and go back to normal." 

Basically you're waging a war on two fronts: your kids and your job. 

I don't know where this weird idea of "Supermom" entered our culture, where magically, somehow, mom was supposed to "do it all", but let's be clear: that's a really stupid idea. And it was probably invented to sell you more crap you don't need...
