A new study came out that showed children who are exposed to television before age three tend to be more aggressive. They included both active television watching, and just having the TV on.
Does this mean we should NEVER have the TV on? Maybe. Is that realistic? Not in my house. Do your best to limit your child’s exposure and try to read to them at least once a day.
