Pregnant women turn to dolphin therapy

In Peru pregnant women are turning to dolphins to make their babies smarter. Scientists say the dolphins' high-pitched squeal actually stimulates brain activity in unborn babies.

Researchers believe it helps with the development of babies' senses.

Women have been lining up to get "dolphin therapy." Dolphins have been trained to swim up to the women and call to their babies. Some women say they feel the response from the babies.
