David Rosen, Gabe Rubin, Michael Harpaz and Andrew Roth find the "buried treasure." ELLYCE FIELD Special to The Jewish News Children's birthday parties don't have to end in an ocean of melted ice cream and screaming kids. Here are some alternatives hatever happened to the old fashioned kid's birth- day party? Six freshly scrubbed kids sitting around the kitchen table, wearing party hats and eating neopolitan ice cream and chocolate cake. A few games — pin the tail- on the donkey, hot potato and musical chairs — some inexpensive gifts for the birthday girl and a yo-yo for each guest to take home. It still exists, with just a little more pizazz and ingenuity. Today's tots are treated to magicians, pup- peteers, horse rides, jugglers and trained monkeys. Children one year and up celebrate birthdays at roller skating rinks, petting zoos and bumper car alleys. Parties are color and theme coordinated. They are major events. Here are some guidelines to steer you safely through the mess of chocolate crumbs, broken toys and wrapping paper fragments in order to plan the almost-perfect birthday party. First, a few ground rules. Make your plans with your child's age in mind. Most one- and two-year-olds are rather blase about birthday par- ties. Often they are too tired, dis- oriented or upset to really have fun. And most two-year-old guests have not learned their party manners yet. By age three, children are will- ing and able to involve themselves in party preparations. Sometimes too fully — as parents who've momen- tarily turned their backs on the birthday cake will attest. Keep your plans attuned to your child's needs. If he is naturally gre- garious, enjoys large crowds, tumult and food fights, give him a birthday extravaganza. Invite his entire class and the kids on the block, including all the trombeniks (troublemakers). Enlist help. Don't let Dad get away with just blowing up the bal- loons, greeting the parents and hanging up coats. He'll enjoy leading games, handing out prizes and serv- ing lunch, too. He might find he's a natural nursery school teacher. Invite older cousins, neighbors and trusted babysitters to help. With pre-schoolers, the more adult hands available, the better the crowd con- trol. And plan ahead. Don't wait until the day of the party to decide where you'll find 32 folding chairs,
