The average American adult will spend a minimum of three hours and 30 minutes on their phones per day and respond to messages in 90 seconds or less. That’s troubling news for older generations, and what is even more troubling is that these habits are trickling down to young Americans.

Too much time on screens can have devastating effects. A study featured in Preventive Medicine Reports showed that teens devoting an average of seven hours or more to screen time were twice as likely to receive a diagnosis for anxiety and/or depression. NPR writes that just five hours or more on smartphones leads to a 71% increase in teens’ likelihood of showing at least one risk factor of suicide!

The good news is that these disturbing trends are far from irreversible. With careful attention, parents can protect toddlers and young children from the ill effects of spending too much time staring at a screen.

1. Set Boundaries

The average adult Internet user will form an opinion about any given web page in 0.05 seconds. Children are much less discerning. As such, it is important for parents to monitor young children’s Internet activity and to set firm boundaries surrounding it.

Make sure you know what websites and applications your child frequents. Keep tabs on any other Internet use. Ask children about their friends and whether they talk to these friends in-person, online, or both. On average, people check their email 74 times a day. Children may fall below this average without the need to check it for work like adults do, but they still tend to check other social media and messaging platforms frequently. Be clear that the Internet, Internet use, devices, and technology are under your supervision, just like household chores and homework. Many parents give their children free rein when it comes to technology. Let kids know they have screen time limits and boundaries stipulating what is and isn’t acceptable online.

2. Make Your Child’s Room A Screen-Free Zone

Do not put a television in your child’s room. Take it even one step further: make it a rule that your child or children can only use smartphones or tablets in the living room and other areas of your home (i.e., not in their bedrooms when they should be sleeping). Blue light emitted from devices can reduce naturally occurring melatonin levels, disturb circadian rhythms, and make it difficult for people of all ages to get restful sleep.

Instead of relying on devices to send your little one to sleep, try making reading a book a regular part of their bedtime routine. Of course, you’ll want to make sure it is a physical book rather than one on a tablet. Nine in 10 consumers believe printed materials will always be needed and the same applies to the literary world. By making your child’s room tech-free, you not only make it easier to establish rules and boundaries but you make sure they are getting adequate sleep as well.

3. Child Lock Apps With In-App Purchases

A full 87% of U.S. families have debt. Giving your child access to apps with in-app purchases and credit card information you saved in your tablet or phone is a recipe for disaster. Stay financially conscious and continue working your way out of debt by utilizing child locks for apps when necessary. Child locks do not require you to delete debit or credit card information from your device entirely. Instead, you can use logins, pin codes, or passwords to bar your child from making in-app or in-game purchases you do not approve.

4. Teach Your Child About Online Security

This one might be tricky, but it’s necessary. About 96% of organizations use cloud technology. That means anything your child does online may be that much more traceable or permanent. Talk to your kids about the permanence of online posts, warn them about talking to strangers on the Internet, and encourage open discussions about bullying, whether it happens in school or on Snapchat. Warn teens that pictures and texts sent are not necessarily private and can remain online for years to come.

5. Encourage Active and Present Play

Now more than ever it is important to encourage kids to be active and present. Make outdoor activities and sports fun again. Take part in these activities with your child–whether it is throwing water balloons, jumping rope or skipping, or coloring with sidewalk chalk outside. For older children, start throwing around the ball, playing tee-ball, kickball, or soccer, or encourage children to join you in themed family fun runs like flavor runs. Flavor runs encourage you and your children to dress in white. During these activities, volunteers shower you with vibrant, bold color flavors that are safe, edible, and leave bright patterns on participants’ clothing. You could get other family members in on the fun as well, such as grandparents. By 2030, an estimated 20% of the U.S. population will be over the age of 65 and it’s important for everyone to participate in active play and put down their electronic devices.

6. Model Good Habits

Young children learn by imitation. In other words, if mommy and daddy are constantly checking their phones, you are unconsciously ingraining these habits in your children and normalizing that behavior. Stay off your phone during meals and whenever you are playing with your child as much as possible.

Plus, constantly checking your phone can send the wrong message. Unfortunately, children are now sharing our time with devices. If you are playing with your child or eating at a restaurant with your child, get a text, check it, and respond immediately, that time spent ignoring your child can take a considerable toll, leading to feelings of anxiety or depression.

7. Don’t Punish Or Reward Kids With Technology

Learn ways to parent and calm children without resorting to handing over your phone or occupying a child with a game on your tablet. Doing this consistently teaches your child to depend on devices. Set screen time limits and stick to them. Treat it like any other activity. Do not bend these boundaries if your child throws a tantrum.

Further, it is also important not to frame technology use in the wrong ways. If you are grounding your child, leave it at that: simply ground them or give them time-outs. Do not specify that you are restricting screen time. Similarly, do not promise kids that they can play video games for three hours if they play outside for at least an hour. That teaches kids that playing outside is a chore or an obligation that must be endured so they can get what they truly want — to play video games. Work on strategies to make these activities equally enjoyable and appealing to your child. In addition, consider helping your child learn how technology helps other people. For example, consider all the ways recycling has helped reduce steel waste. Almost 40% of steel production around the world is made with recycled metal, thanks to advanced recycling technology.

About 53% of children have their very own smartphone by age 11, according to NPR. The average age of at least some smartphone use recently decreased from 4 years to just 4 months old. Parents need to step in and do something about it. Talk to your child, be present with your child, and do what you can to form healthy habits around modern tech.
