It's never too early to teach your child to be of use around the house, right? There's a whole series of these books, with titles such as "Baby mix me a drink" and "Baby fix my car". I'm waiting for "Baby write me a best-seller".
Baby's gotta learn to be useful. Raise 'em right from the start. Teach 'em to make you breakfast. And as far as vocabulary goes, 'over easy' is much more useful than "fire truck".
