M.,
Here's what I do for every birthday because there are too many people, you can't make everyone happy, and the stress isn't worth the party.
Drinks:
1 2liter of each: pepsi, coke, diet pepsi, mountain dew, dr. pepper.
Make a picture of sweet tea and one of unsweet.
1 bag of each: Doritos, lays, cheetos, and tostitos
make one lipton onion dip and get cheese salsa and regular salsa.
Buy 1 large watermelon, 1 cantelope, and one honeydew.
Using an ice cream scoop, measuring spoons (1/8 cup and 1/4 cup and 1/2 cup) make balls with fruit and when finished put balls back in rind. Easy clean up what ever is left put in the trash, no dishes.
1 large block each: Colby jack, monterey pepper, and swiss cheeses.
1 box each: ritz and saltine crackers
pepperoni or summer sausage.
All of this can be taken care of before hand and all is easy to prepare and clean up.
Remember no one cares what is there or isn't all they will remember is that they were there to celebrate the first of many birthdays with your child. That's special.
OH don't forget the cake!
Have fun and Best of Luck!
J.
