We had a BYOB (Bring your own Banana) party for my daughter's 1st birthday.  It was a huge hit!  On the invitation was a picture of Annie with a banana and different flavors of ica cream and toppings around her.  The front read "It's a banana split party for our little girl named Annie, no need to bring a gift, just bring your own "bananie". At the party we had a buffet of ice cream, toppings and other ice cream treats. I purchased banana split bowls from a party supply store.  We decorated with primary colored balloons and table cloths. It was a great time and everyone got to make their own banana splits! Guests are asking if we are doing it again this year!
