I am having a Birthday Party for my daughter on the 4th of July. her birthday is in the end of June and we just decided to bump the party until the 4th. She will be turning 5. I also have a son that is almost three and all the kids at the party are close to these ages. I would like to have something fun for the kids to do yet they are all to young for fireworks. Any fun 4th of July party ideas for kids under 5?
