What 2 year old doesn't like balloons?!? So we decorated with tons of balloons (well not tons, but 2 pacakges) including the huge ones with rubberbands attached. They make for interesting boxing matches.
And another with mommy & baby Gracie. She loves her lil' sister already (however, I look less than thrilled...hmmm...mental note, don't explain the camera while being the subject)
