Watching television makes it easier for toddlers   to kick and scream, according to a US study.Children under two should not watch any TV.The longer they sit in front of TV,the worse their behavior becomes. Just having the TV on in the background, even if the child wasn't watching it,was also connected to troublemaking behavior although the relationship wasn't as strong, said the researchers. "Parents should be smart about TV use,"researcher Jennifer Manganello from the University at Albany, New York, said. "They should limit the time that children use TV, pay attention to the content of TV programs,and consider how TV is used throughout the home." The study looked at 3,128 women from 20 US cities who had a child between 2005 and 2008. While there was some diversity  of education among the women,onethird hadn't graduated from high school. Twothirds of the mothers said their threeyearold children watched more than two hours of TV a day,and the average viewing time for children was around three hours.On average,the TV was on for about five additional hours on a common day. After accounting for factors  such as living in a violent neighborhood,scientists also found watching TV was strongly connected to behavior such as hitting others,having angry moods,being disobedient ,and screaming a lot. The researchers thought that children may see violence on TV,and spend less time on positive development tasks such as reading or playing. The American Academy of Pediatrics suggests no TV at all for children at two and younger,and two hours a day or less for older kids. What can be learned about the study between 2005 and 2008 from the passage?
The women studied have different jobs. The TV was on for about three hours. Most women allowed their children to watch TV. Most women studied hadn't graduated from high school.
