I could use some party theme ideas for a 4 yr old son's bday party

Planning parties can be so much fun especially choosing a theme that children like. At this age children are into trains and cars. Thomas is a great theme for a party because there are a lot of activities and favors that you can find. Pin the number on Thomas is a really fun game to play and you can get the Thomas cake toppers for your cupcakes and leave each child with a keepsake ring after they have eaten the cake. You can even get the children to participate in coloring Thomas. Spiderman is also a good idea for a four year old who also loves super heros. Cars is another theme that is great because you know every child loves lightning McQueen, the hot rod. I can go on and on, but these should help.
