For my son, we did a vintage Peter Pan them with an emphasis on the pirates. I just made a big pot of pulled pork and had chips on the side. I ordered cupcakes from a local bakery. I kept it fairly simple, but did create little cards to put them around the house with quotes from the book (Mermaid Lagoon was by the punch, etc.)
My daughter's first birthday we did a Lemonade theme, so everything was pink and yellow. We used a wooden crate and some other leftover materials and created a tiny lemonade stand, which turned out great for her photos. I just picked up some chicken salad from a local restaurant and some breads, served chips, and lemonade (of course). Again, we just kept it simple but still had fun.
