My sons birthdays are a week apart so we celebrated our 3 year old and 1 year old with a sports party! The entertainment was free, because we just emptied out our sons closet of ALL of his sports equipment & games and let the kids go at it! They had a blast playing basketball, baseball, football, soccer, badminton, bowling and even angry birds! :) I had a concession stand complete with hot dogs, ball park nachos, preztels, peanuts and popcorn. Gatorade and rootbeer were the drinks of choice and for favors I let everyone choose their favorite ballpark treat on the way out...popcorn, cracker jacks or sunflower seeds. I made everything myself to keep the cost down and I think it turned out pretty cute! Except my one year missed his own party b/c he got a fever the night before and couldn't come. :( No one got to see their cute matching outfits.
