Let's face it, you've now got 2 and a half full-time jobs: one is whatever you do for work full-time, and the other 1.5 is taking care of your kids (because we all know that's a full-time job and then some).
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."
It hasn't happened. Sadly, it doesn't look like it will...
