With all the running around mommies and daddies have to do on a typical children's party, some things are bound to be overlooked.  Here is a list of things that you should check on before the big day:

THEME
Do you or your celebrant prefer a specific color sheme (e.g. pink and red; all shades of blue, etc), a favorite cartoon character (e.g. Barney or Dora), a movie (e.g. Finding Nemo, High School Musical), a place (e.g Under the Sea, Jungle), a TV series (e.g. Wonderpets, Backyardigans), objects attractive to kids (e.g. bees and butterflies, flowers and fairies).
