Got milk?

Last night at the dinner table, Ethan pointed at his biceps and said, "I've been working on these!" It seems my encouragement to the kids to eat and drink various things because of their nutritional benefits is paying off, although he's confused bones with muscles. He thinks that all the milk he drinks is making him very strong. We often catch Megan taking a drink of her milk and then checking out her bicep, like she can see it grow. If only it were that simple.
