Go Jump in the Lake! It takes on a new and really fun meaning when you invite some friends to literally jump in the lake with you- over and over and over! My kids were given a gift of a water bouncer as a joint birthday present this year from their grandmom, and so that became the theme of my son's birthday party. We added things that we see at lake a lot- like fox, fish, bugs, and a skunk (there is one that lives in the woods around the lakehouse that is very cute- we just hope we keep it happy!). Hopefully, you can find some fun and easy birthday party ideas for a similar theme- such as a camping party, fishing party, or woodland animal theme!
