Good for you, girl! I am also a woman who appreciates a good theme!! I would suggest probably 10 games because having more than 2 kids/booth might be a bit much. Here are a few ideas I had:
Lollipop tree: get a couple of bags of dum-dum pops and color the bottom of a handful with red marker. Stick them all into a piece of styrofoam cone. The kids can choose one. If it's red, they get a prize and the lollipop, if it's not red they just get the lollipop.
Duck Pond: get a bunch of cheap-o rubber ducks (try Oriental Trading Co) and float them in some sort of a tub. Either mark each one with a number and have different prize bins of corresponding numbers, or do the same thing as the lollipop tree and if they get one with a mark, they get a prize
Ring toss: get some frisbees with the center cut out (again check Oriental Trading Co or Wal Mart) and have them toss them onto 2 liter bottles. YOu can fill the bottles with water or sand to help them stand up sturdier.
Bottle Game: collect empty bottles of the same size (milk, soda, water, gatorade) stack them in a pyramid shape and have kids knock them over with a soft ball or balled-up socks
First Aid station: have plenty of cheap band-aids and guaze wrap and tape and let the kids cover up some "boo boos" with all the stuff.
Bean Bag toss: make a bullseye and have them toss 3 bags towards it...if it gets in center get a prize
Bowling
Free throws: if you have one of those Fisher Price stand-up basketball goals (or could borrow one) give them 3 tries to make a free throw
cake walk: instead of doing cakes, maybe do cupcakes or cookies instead because they sure don't need a whole cake! Or you could do Little Debbie cakes.
Okay, so I know this is a lot of info! Hopefully there is something in here you can use! Have fun and go crazy!! :)
