A 2nd birthday party should have a theme that interests the child, such as princesses or trains. The party can also be decorated with the child's favorite colors.
For a princess-themed party, purchase foam crowns and let the guests decorate their crowns with plastic jewels and glitter. For a birthday party with a train theme, give the children train whistles or conductor hats as party favors. If the toddler has a favorite cartoon or movie character, the character can serve as the party's theme. For example, if the 2 year old loves Mickey Mouse, the plates, banners and birthday cake should feature pictures of the Disney character.
