Rub-a-dub-dub, thanks for the grub!

Is it us or does the amount of food in a household go up exponentially with each additional person? I suppose over time we'll figure out how much of what to get (and how often), but from the amount of milk, bread, yogurt, fruit, and meat we are getting, you'd think that's all we eat.

Which may not be too far from the truth, come to think of it...
