We celebrated being three by having a barn yard party at a local park. We bought a couple of bales of hay for reading stories about barn yards and story telling. Planted broccoli and cauliflower in bright colored buckets and everyone took them home in place of goodie bags. We had tug o war and sack races. We made dirt cake in individual cups with gummy worms. We had face painting of our favorite barn yard animals. Everyone came dressed in overalls. It was a lot of fun for the kids and adults. A petting zoo would have been a great addition. It takes a little planning, but the fun was well worth it.
