I went to a 2 year old's birthday party. I bought her bubbles -- I got each kid at the party their own bubble stuff (mini size) and got her a big canister of bubble mix and a battery operated little bubble gun that shoots a ton of bubbles at one time. She was so delighted. In fact she was so thrilled she laid on top of her birthday cake and yelled, "YEAH YEAH!!!" The cake was a mess and so was she. But everything was great!
