Here’s another Parent Hack that could work just as easily in your professional office:

As the party came to an end, each pint-sized guest (and sibling, if there was one) received a wrapped party favor with his or her name written on it. Turns out the birthday boy's mom, Mary Wells, had gone to our local library's used bookstore and hand-picked a book for each kid. It doesn't get better than that!

Stock your waiting room with a bookcase full of used books, which cost (at my local library, at least) between twenty-five cents and a dollar.  If a client, or a client’s child, likes a particular book, let them take it home with them.
