Children in the United States are spending more time in front of screens-watching television, movies, and using computers- than ever before. They are spending much more time with these types of media than with books or in free play, and it is happening at younger and younger ages. Parents are not just “letting” their children watch but are often actively encouraging these forms of passive entertainment. TV is a cheap and always available babysitter, so it’s no wonder parents sometimes rely on it to keep kids busy while grown-ups take care of household chores, bills, or catch up on their emails.
Children under two spend, on average, more than two hours every day watching TV or using other screen media like computer games and video games. But according to the American Academy of Pediatrics, children under 2 should not be watching TV, videos, or DVDs at all. In fact, the Academy recommends no “screen time” for babies and toddlers. Parents should instead encourage more interactive activities such as playing and talking. The American Academy of Pediatrics first announced this in 1999, but most parents are unaware of this advice: either their pediatrician never mentioned it or parents figure time in front of a screen is harmless or even educational, provided children are watching the “right programs.”
Research shows that, for children under 3, it’s not just what’s on TV that matters but that it’s on at all. Even if the TV is simply “on” in the room where the child is playing, there are negative effects. A study in 2008 found that when an adult TV program was on in the room where babies or toddlers were playing, the children didn’t play as intently or as long as when the TV was off. “Background TV” also affects how a child interacts with his or her parents. When the TV is on, parents tend to be more distracted and less attuned to their children and their needs, reducing the quality of the interaction.Young children are better able to complete complex and sophisticated tasks when they work with an adult or older child. When parents are attentive, children are also more likely to engage in independent goal-oriented play, higher quality play, and more focused play.
What about TV programs intended for young children?
TV programs meant for babies and toddlers don’t really help them learn, and in some cases may slow down their learning. The more TV a child under 3 watches, the more likely he is to have trouble with reading and paying attention later on., A study from 2007 found that the more television a baby 8 to 16 months watches, the fewer words she knows. It doesn’t matter if she’s watching educational programs such as “Blues Clues” or “Sesame Street” because babies learn by interacting with real people-not screens. Early childhood experts agree that because infants and toddlers learn differently from older children and adults, they don’t benefit from direct teaching, which is the technique most commonly used in “educational” TV shows and baby videos. Baby Einstein brand videos are just one of the many videos developed and marketed to parents of very young children as “educational.” But with research showing no benefit, and under threat of a class-action lawsuit for deceptive advertising, Disney began offering refunds for the videos in 2009.
Not only has screen time been linked to language delay and smaller vocabularies, but studies show that the more television infants and toddlers are exposed to, the more likely they are to be inactive and obese, have difficulty sleeping,and show aggression. A study published in 2009 found that the more TV a three year old was exposed to (watching it or in the room where the television is on), the more likely he or she was to act aggressively. Screens provide a lot of stimulation, but it’s all energy “in” and no energy “out” or expended. This may explain why young children act out after hours of watching, and why hours in front of the TV can lead to weight gain. There are several reasons why children who spend a lot of time watching TV put on extra pounds: the number of food ads they are exposed to while watching can increase their appetites; many kids get into the habit of snacking while watching; and they burn off very few calories burned while watching.
Very young children learn best by relating to real live people, but they also learn by moving and doing. Part of the problem with screen time is that young children who watch TV and DVDs or use computer games may be substituting these activities for free play. Play, as it turns out, is the ultimate “personalized educational curriculum,” with each child creating his own challenges and solutions-at little or no cost. It teaches children to think abstractly about different situations and learn from other people’s perspectives, and it taps into their curiosity, motivating them to learn. Play provides children with opportunities for different types of learning-physical, social, emotional, intellectual, and language development-in a context they understand. Because of this, children are more likely to retain what they learn while playing. This is why child development experts insist that play is essential to social, cognitive, emotional, physical and moral development.
Children’s media exposure
So if play is the real teacher and the best babysitter, how do we fire the TV? How do we limit children’s exposure when TVs are everywhere? The average household has 3 television sets, and 19% of children less than one year old have one in their bedroom! For children between two and three years old, the percent who have televisions in their bedroom jumps to 29%. TVs are present and watched in most child care centers, too. Whether it’s home-based child care or a center-based child care setting, children often watch TV as part of their daily routine. It is estimated that children watch 2-3 hours of TV in home-based child care settings per day and about 1.5 in center-based child care settings.
Some parents and early childhood settings are replacing televisions with computers. While computers can be terrific teaching tools, too much time in front of a computer can lead to some of the same problems as too much time watching TV, such as obesity. According to one study, children ages 4 to 7 who were overweight were able to become more physically active by parents’ cutting their screen time in half, including computer use.
What about school age children and teens?
With media use on the rise, screens are not only in every home, but in every pocket. In a 2010 study by the Kaiser Family Foundation, researchers found that youth age 8-18 use an average of 7 ½ hours of media each day, including TV, computers, cell phones, and music players. All of us-not just children and teens-have been affected by the spike in media consumption: we spend less time reading and less time sleeping.,
Spending a lot of time in front of screens in the early years can lead to increased screen time later in childhood, which may contribute to problems with peers and at school. While media use itself may not be the cause, kids who spend a lot of time using media, tend to get lower grades. One study allowed 12 to 14-years olds to play computer games for a long time or watch a lot of television and found that both types of entertainment affected sleep, and the computer games also affected the children’s performance on certain memory tests. Research also shows that children and teens who watch a lot of television are more likely to have health and behavior problems, including drinking and taking drugs. The more movies and TV that children in grades 5-8 watch where characters or actors are smoking, the more likely children are to smoke later on.
So what’s a parent to do?
Very young children have nothing to gain and lots to lose from spending time in front of screens, instead of playing and interacting with friends and loved ones. Even when the TV is simply on in the background, infants and toddlers lose out. For older children (two and up), the American Academy of Pediatrics recommends that parents limit screen time to 1-2 hours a day, and keep televisions in common areas-never in a child’s bedroom. TiVo, DVRs and other devices are terrific tools for parents, allowing them to record shows for children that can be seen by them at an hour that’s right for your family’s sleep schedule and without commercials!
Here are some ways you can limit screen exposure and increase interactive play:
- Get your toddlers and pre-school age children involved in household chores and let it be a learning opportunity. You can get them small brooms so they can sweep one part of the room while you sweep another, and you can teach them the names and colors of vegetables while you are cooking.
- Make it a point to eat dinner together and ask your child about his or her day. If it is a very young child, you can remind him of all the things he did that day, asking a few simple questions, such as what he liked best about the day.
- If you really need your child to be occupied during an important call or while you complete a task and you don’t think that she will be able to play long enough by herself, let her listen to pre-recorded stories on a tape or CD. You can buy these but better yet, record yourself telling or reading your child’s favorite stories. This way your child will have you, even when you are not available or are away on a trip. Listening to stories, as opposed to watching them on TV or on a computer, helps children develop listening skills.
- When you want to watch an adult show, record it and watch it after your child goes to sleep.
- If your child is going to watch something, watch with her and comment or ask questions about what you are watching. You can make passive TV viewing active this way.
- Provide your young child with simple toys and household objects that aren’t automated (if the toy needs batteries, save it for when the child is older). The more the toy does, the less your child will do.(Remember the “personalized educational curriculum”!)
