To put this into perspective, young children have an average amount of 16 colds per year (there's even a cool repo for incidence data, I suspect you could get more precise [1]). With an increasing number of parents both being in the labor market, and with childcare facilities increasingly (and rightfully IMO) refusing to take in sick kids, this means that parents need to take their own sick days to care for them.

It's difficult to do a back of the napkin calculation, but you can easily see how 16 colds x 3 days / 2 parents leads to 24 excess sick days for parents per kid (discounting for some overlap when multiple kids are sick) over the first few years.
