Does my 7-year-old grandson play too many computer games with his dad?

January 25, 2010

Q: My 7-year-old grandson comes home from visits with his dad talking non-stop about a computer game marked for ages 10+ that they play together. What would be a good amount of time for him to be allowed to play a game like this, and can it cause him to become addicted?
