You could do the traditional teddy bear. Wilton has a great Stand up Teddy cake pan. For my son's first b-day, I did a farm theme (he loves animals) I mad the invitations. I cut red construction paper in the shape of the Barn. And put, Old Mac"Jackson" is turning One. And on the inside put
E I E I O, and the party info. I did a whole farm cake complete with barn, pond, pretzel fence. Frosted Pretzel corn field with oreo dirt. (I love making cakes). You could also do something as simple as a round cake frosted white with black cow spots. I had checkered table clothes and had a camp fire and we had a weinie roast and made smores (great fun for the adults and older kids). We played find the cow in the sandbox. I hid several different animals in the sandbox. Everyone got to keep the plastic animal they found and the person that found the cow got an exta prize. (I bought $2-5 gifts for every child that attended the party and we played games for them to win a prize). We had a 3 legged race. Child with adult. Every one had a great time. I did a sesame street theme for my daughter first party. ELMO! For her second birthday we did bugs and went on a bug hunt. You could do a "crockadile hunter" theme and go on a safari in your back yard. Have treats like croc eyes (grapes) bug wings (chips) gummy worms. do a paper bag pinata. I have a ton of ideas. Just let me know what your son likes right now and I would be more than happy to send you my ideas.
