I don't see the big deal. I also let my DD watch the news with me. Most of it, she doesn't seem to pay attention to. However, the things that do grab her attention, I use as a learning tool. She will learn about the "bad" things in life with or with out me. I would rather her learn the truth from me, then to hear a friends version of the truth (like in my day the truth about sex I heard from friends was MUCH different than the real truth.
). This way, if she has any questions or concerns, I can help her understand. I just reiterate things in a way she can understand better.
This incident happened not too far from here, so I think we were exposed to this more so then someone living in, say, California has been. I used this as a continuing education to that about the cruelty of animals. Last year, in preschool, her class raised ducks from eggs to adult hood. Her first thought was "were these the ones we saw hatch?".
She was quite relieved to find out that they weren't, but she also made the comment "That's mean! Why did that man hurt them? He should pick on someone his own size!".
Besides, we will be at TI in a few weeks for the Dana Farber Roadrace. I would rather answer questions now than have to explain things to her then.
I can only hope that as she gets older (like teenage years) she will still be this open & honest with me. I know I talk to her more about "everyday life" than her father does. I notice that now if she has a problem with something (other than sports, lol ) she will come to me before she goes to my husband.
Bottom line, I feel a child needs to be taught right from wrong BEFORE they are teenagers. If you wait, it could be too late!
It is never too early to start teaching a child (at their level)....whether it is stranger danger, animal cruelty, how to use 911, avoiding stereotypes, etc...
