How many kids? She has twins.

A long time ago, when I had only one child I made a joke to one of my coworkers that had twins. It was something like that child care was O(N), so she had the double of problems.

Now I have two small children (and a big one), and now I'm convinced that it's at least O(N^2). [In my case O(5) not O(9), because the old one is old enough.]

It's not really about the amount of work needed to parent. It's more about letting go until the amount of work matches your capacity plus some time for other things.

For the people in my life that sound similar to the OP they do the reverse. They add parenting work until their capacity is full. If you gave them and extra 3 hours in the day they'd still be just as busy.
