My girls birthdays are a day apart. They often share a party. Last year we had a survivor party with 20 kids. It was in january so had to be all indoors. We prepared plates with food children did not like, lemons, green beans, gummy bugs, pickles etc. For a food challenge each child had to draw a number, which coresponded with a plate which they had to eat to meet the challenge. We also had divided into two teams and each team were given poster paper and paints and markers to design their team flag. We aslo had a relay game. The children had so much fun doing this that they wanted to play again and again. We then had a scavenger hunt for presents the team that found the most won. It was a blast for all the kids ages 3 to 12.
