When you are 4 years old, and you’ve had a long, hard day at work playing with kids who have cats for pets, often the best thing you can do is sneeze, itch, and come home and have a good cry. Preferably on watercraft-sized breasts, which I can assure you is one of the few times they are appreciated by their owner. Of course, an antihistamine and some eye drops help, too.
After that, the only thing you can do is shut your eyes and cover them with a cool, wet, washcloth (or paper towel if the parental units remain alarmingly unprepared for such things). Then, you simply rest.
Until everything is all better. Conveniently enough, 3 out of 4 pediatricians agree the same course of treatment also works for things like recessions and potential lay offs.
