Three most common words heard around here these days: "Mom, I'm hungry."

I have given birth to a freaking eating machine. He's five, and already he will eat for lunch a hotdog (or two), a string cheese, a whole orange, and a glass of milk, followed by a yogurt or some other dessert and an hour later he will be hungry again. Genuinely hungry.

He's perfectly normal height- and weightwise, so I'm not worried about it in that regard. I just worry about what the heck I am going to do to put food in the pantry when he's 15 if he's already eating like a horse at five.
