'Supernanny' star Jo Frost has quit the hit ABC reality series to start her own family.

According to the New York Post, Frost will tape one more season of the series focusing on teen mothers.

"I have decided to hang up my cape," she told the newspaper. "It was a very conscious decision, through much reflection. But I need to create more balance in my life."

Frost has been traveling the U.S. and Britain since 2004, helping parents with unruly kids, but now she wants to focus on her own life and start a family. "Proper balance will allow me to date and have a relationship and look at my own future of having a family," she said.
