Today, I explained to my 4-year-old that women have babies and men don't. And that the reason I was so sick last summer was because I had his baby sister in my tummy. "Mommy, thank God I am not a woman," Caden says. "Because I don't want to throw up in the toilet like you did all summer. And I don't want to have a fat belly." Ah, from the mouth of babes.
