Hi A.!
Our first, Emma Kate just turned 1 on October 5th! We did a bar-b-que with bugers & hot dogs and had some sides for the food. I did a whole pink & green theme, so I had pink & green cupcakes on two cupcake trees (you can get them at Target and Michael's, and they're SO cute to display cupcakes on). The cupcakes were great for everyone... easy and no plates needed! Her invitations were big lollipops with pink & green swirls, so I made sugar cookes-on-a-stick and "painted" them with pink & green icing, wrapped celophane around them with ribbon... these were the favors. For the safari theme, you could get cookie cutters in animal shapes or they have those cupcake cakes now where its a bunch of cupcakes put together and the frosting covers all of them. I bet you could get the store or bakery to do a cute monkey or lion or something.
For something for the adults to do... I boght a small scrapbook that I am scrapbooking her first birthday in (my goal is to do a book for each birthday). I was careful to take pictures of each guest/family (not awkwardly, candids are fine) and I set out cards/pieces of paper matching the theme of her book and pens. I asked everyone to write a special note to Emma to go in her book. For the kids, I set out crayons and they each drew her a picture. It turned out really cute. One of our friends' 5-year-old little boys drew a picture for Emma of his daddy on the toilet! HAHA! We'll laugh at that in her book for years! I know I would have loved looking at a book like that when I was little, and I'm excited to see Emma Kate enjoy it as she grows up!
Good luck and enjoy your little one's first birthday! It IS for the baby, but I think it's really like an anniversary of becoming parents for you and your husband, too! I know Emma's first birthday was really special to me. So don't feel bad about that... and have fun!
