It sounds like your finger food list is great!! So why not look for variations on those core basics? Dip some of your fruit in Chocolate. Incorporate different fruits like kiwi or try cutting out some fruit with cookie cutters in fun little one shapes! One year we cut our Peanut Butter and Jelly Sandwiches into shapes (themed to go with the party, of course *wink*).
Have fun, scour the web using your current menu to find those new twists...if I knew the theme I would have tried to look up a few cute ideas for you. Happy Birthday Tucker!!
