"Nose the Balloon"
Let the kids make teams of two. Each team gets a large balloon they must blow up. Between them, they must keep the balloon in the air bumping it only with their noses. Each time it falls on the ground they loose a point - each team starting with say 100 points. The team who takes the longest to loose all its points is the winner.
"Stomp the Balloon"
Each kid gets a balloon and a piece of string about a yard long. They must blow up the balloon and tie the string to the balloon and to his ankle. There should be enough string between the foot and the balloon. The kids must now try to stomp and pop each other's balloons. The winner is the last one with an un popped balloon.
"Playing In Paint"
Ok so admit it you grown ups would love plaint in some messy paint, its sure to be a fun time with your little ones (even the big ones love it)
So put your protection down on the floor or table, (or if it's a nice day go outside).
Get lots of children's paint and have lots of FUN.
Enjoy :)
