Researchers from the University of Texas at Austin and University of Michigan looked at 75 studies involving more than 150,000 children over 50 years. They found that children who were spanked were more likely to defy their parents.

Family discussions about discipline can often leave a house divided.

“We talk to them, we try to figure out this is what we need to do and this is what we should do. We don’t do the whole spanking thing,” said Jennifer Jarvis.

She says just talking about it is enough to bring her daughter to tears.

“I’m not even mad or angry and look, she’s about to cry,” she said.
