Does anyone have suggestions for an activity or game for a 1st birthday party so that a group of almost 3 year olds aren't bored/running around like crazy? Thinking there will be about 25-30 people at my LOs 1st birthday party, but want to make sure that we have something planned to keep the older kids occupied. The birthday party is going to have a spring flowers theme, but haven't decided on a menu yet.

Any ideas?
