I thought a lot of things before I had children. With three boys, ages 15, 12 and 6, I know better now. (And with a teenager, I have a feeling my toughest lessons are still to come!) One of the things I heard was, "How on earth can a toddler's mother be overweight? Chasing her kid should keep her skinny!" To be fair, I never said it, because it's mean as all git-out, but it made a little bit of sense. Until I had toddlers.
