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 Carlisle, 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.
