Monday's school shooting raises some tough questions for parents. Should you discuss it with your children, and how? Child Psychologist Gina Leggett suggests you bring it up. Ask if they've seen it on TV. Ask them is they've talked about it at school and what they think? Also talk to them about safety at their school. Leggett also suggests limiting a child's exposure to TV if you know a violent image will likely be played over and over again.
