New research shows more children are swearing at younger ages than has been recorded in the past 30 years.
Timothy Jay, a Massachusetts College of Liberal Arts psychology professor, recently presented his findings at an international conference. He found children as young as two years of age were using swear words.
"By the time kids go to school now, they're saying all the words that we try to protect them from on television," Jay told the Montreal Gazette. "We find their swearing really takes off between three and four."
Researchers believe children may be learning the bad words from their parents. It turns out two-thirds of adults with no-swear policies for their kids, actually break their own rules at home.
"I was fighting with my sister and I said a bad word to her," one child said on ABC's Good Morning America program broadcast Monday. "I know I didn't learn it at school."
Jay believes children are like little vacuums -- absorbing all of the words and phrases that they hear.
"As soon as kids can speak, they're using swear words," Jay said. "That doesn't mean they know what adults know, but they do repeat the words they hear."
Some kids are fighting back against the trend. A middle school boy in California started the No Cussing Club four years ago. Today, the club boasts more than 20,000 members in all 50 U.S. states and around the world.
