Have each child bring a wrapped book and do a book swap. This serves as the birthday gifts and the party favors!
Have the kids make a craft, and let that be the party favor as well.
Record interviews with the birthday boy/girl with each of the party guests and give copies to the guests as party favors.
Have a “Bring Your Own Vehicle” party with bikes, tricycles, Big Wheels, and other riding toys.
Let the party guests decorate their own cupcakes or build their own ice cream sundaes.
Buy a plain cake from a local bakery, and then decorate it yourself using figurines, paper cutouts, etc.
Make your own banners from scrapbook paper, cardstock, and ribbon. Then reuse them for your other parties.
Let the party guests create their own personal pizzas.
Find someone who works with animals and would give a free presentation (though a donation would probably be appreciated). This could be the theme/entertainment for your party. Example:www.percykingsnakes.com.
