A child's birthday party doesn't have to be a hassle; it can be a basket of fun, according to Beth Anaclerio, an Evaston mother of two, ages 4 and 18 months.
  "Having a party at home usually requires a lot of running around on the part of the parents, and often the birthday boy or girl gets lost in wild excitement. But it really doesn't have to be that way," said Anaclerio. Last summer, Anaclerio and her friend Jill Garlisle, a Northbrook mother of a 2-year-old, founded a home party-planning business called "A Party in a Basket." Their goal is to help parents and children share in the fun part of party planning, like choosing the subject or making a cake, while they take care of everything.
  Drawing on their experiences as mothers, they have created(制作)10 ready-to-use, home party packages. Everything a family needs to plan a party, except the cake and ice cream, is delivered to the home in a large basket.
  "Our parties are aimed for children 2 to 10."Anaclerio said, "and they're very interactive(互动)and creative in that they build a sense of drama based on a subject. For example, at the Soda Shoppe party the guests become waiters and waitresses and build wonderful ice cream creations."
  The standard $200 package for eight children includes a basket filled with invitations, gifts, games and prizes, paper goods, a party planner and the like. For more information, call Anaclerio at 708-864-6584 or Carlisle at 708-205-9141.
