As the trend toward an awake and aware childbirth experience accelerates, the demand for childbirth preparation courses has increased. Parent and Child, one of the volunteer organizations offering prepared childbirth courses in the Washington area, taught 1,700 couples in 1976 and nearly 3,000 in 1977.

The number of couples we can serve is limited only by our own capacity. We're looking for new locations for teaching sites in order to accommodate the demand, which seems to increase 25 to 30 per cent a year," said Iris Cross, chairman of Parent and Child's board of directors.

Courses in childbirth preparation usually are taken during the eighth month of pregnancy. Because of the demand, early registration is advised.
