I am so glad I'm not the only mother who gets grossed out by the same things that enthrall her children. My kids love to talk about it more-why is that? They laugh every time the word "fart" or "booger" comes up, like it's the last thing they'll ever laugh about. I did read somewhere that it's somehow linked with boys and their genes, to be entertained by gross things, specifically potty talk, and the advice was that it will end around the age of 13. Well, for one thing, great! My son is almost 4, so in 9 years, we'll be golden. And 2, my husband is 31-when is the amusement going to end for him?
