For my girlfriend, I made cinnamon sugar and put it into shakers with tags that read "Sugar and spice and everything nice..." but she was having a girl.
One super-cute thing I saw for a baby boy shower was a variety of cookie cutters - trains, cars, baseball bats, footballs - with ribbons attached. Another cute thing was a seed packet for herbs that you can plant in a pot in your kitchen. And M&Ms does personalized candies with messages on them. There are so many options!
