BEUING (Associated Press 美联社) —China has a growing middle class, a tradition of expecting education and 21 million new babies every year. Selling educational toys should be easy.

While China may be the world’s biggest toy maker, many of the best are exported. Department stores here do not have enough toys of high quality. It is said that the demand for educational toys is low.

A US company, Baby Care, is trying to change that with a new way to sell toys in China.

Baby Care works basically together with doctors in Beijing hospitals.  People who join the company’s "mother club" can get lectures and newsletters on baby and child development at no extra cost, if they agree to spend 18 dollars a month on the company’s educational toys and child-care books.

"We want to build a seven year relationship with those people," said Matthew J. Estes, Baby Care’s president. "It starts during pregnancy (孕期), when the anxiety and needs are highest." Baby Care works on a one-to-one basis. Doctors, nurses, and teachers paid by Baby Care advise parents and explain toys that are designed for children at each stage of development to age six.

Baby Care opened its first store in China last June in a shopping center in central Beijing and another near Beijing Zoo. It plans to have 80 stores in China within six years.

It is a new model for China and develops a market in young children’s education and health that no other companies are in.
