Possibly useful to get parents to open up.
It just seems so weird that you wouldn't tell your kid about Covid. Is the culture that different in the Phillipines, where the book was published? It's written to be applicable to anywhere you have apartments and doctors. Do they not have Kindergarten? Because that's one major reason my six-year-old knows about Covid: he had to stop going to school in person, and start doing Zoom calls.
