Do you have an MP3 player? If so, you could set up a playlist in advance and hook it up to speakers at the party for background music, or, if your hubby is like mine, he could play DJ and take requests. For my son's birthday we played simple games with the older kids like bingo, limbo, pin the tail on the donkey, and hot potato. I had also planned a craft, but we didn't get to it (I had art supplies to make paper bag puppets). Your son is too little to really get involved in any of the games/crafts, so really it's up to you how far you want to go to entertain the other kids at the party. Heck, my son fell asleep before we even got to open the gifts!! Just make it fun and easy on yourself as possible.
