Because you will be working on the electrical system of your car, it's important to disconnect the battery before you get started. If you aren't sure where to locate the battery in your vehicle, refer to your owner's manual; most car batteries can be found under the hood, but some are kept in the trunk. Once you locate the battery, use a hand or socket wrench to loosen the black cable from the negative terminal on the battery. You will not need to remove the bolt entirely, instead simply loosen it enough to pull the cable off of the terminal. Tuck the cable down to the side of the battery so that it can't come back into contact with the terminal. You do not need to remove the battery or disconnect the cable from the positive terminal. To be sure the battery is disconnected, check to see if the lights come on in the cabin of the car. Nothing electronic should work with the battery disconnected. Disconnecting the battery will prevent you from doing damage to the electrical system as well as protect you from shocks. You will need to gain access to the sides of the stock head unit (or stereo) in your center console. In some cars, that will require the removal of some pieces of plastic trim. Be careful when removing trim pieces, as they may be brittle and subject to cracking. Whenever possible, try to pull the piece of trim out slightly to get a look at what kind of clip is used to attach it. You may need to slide the trim piece in a certain direction to separate it, you may need to hit a release with a screw driver, or you may need to simply pull on it hard enough. Checking first will prevent you from breaking off the clips and having to replace the piece of trim. Consult your car's repair manual if you want to determine the best way to remove pieces of trim that are in your way. Set the trim aside where you won't accidentally sit or step on it as you work. Car stereos are all held in place using one of two methods: spring clips or bolts. Each method requires a different technique for removal. In order to determine what method your car uses to secure the stereo, you can consult your car's repair manual or look closely once you've gotten the trim out of the way. Spring clip mounts may not require the removal of any trim pieces and can be identified by the matching pairs of holes on either side of the stereo. Stereos that are bolted into place may require more trim removal, as you will need to gain access to the space behind the stereo. Look for two pairs of matching holes on the left and ride side of the stereo. If they are present, your stereo is held in place with spring clips. If there are no holes, remove the trim below, above or to the side of the stereo to gain access to the bolts. If your stereo or head unit is held in place using spring clips, you will need to purchase a pair of DIN tools. DIN tools look like thin pieces of metal bent into the shape of the letter "U" with slightly hooked ends. Insert one DIN tool into the two holes on the left, and another into the two holes on the right. Press them both in until you hear the click of the spring releasing. Spread the tools apart slightly to grip the back of the stereo and pull the tools toward yourself. The stereo will slide out of the console of the car along with the tools. In a bind, you may be able to use pieces of a metal coat hanger to create your own DIN tools. If the stereo doesn't come out, it is likely stuck by a piece of trim. Don't force it out, instead look for any obstructions that may be preventing it from moving. You will likely need to remove quite a bit more of the trim to access bolts that hold your stereo in place than you would have with spring clipped stereos. Once you are able to see the bolts, removing the stereo should be fairly self-explanatory: there will likely be four bolts, either attaching the stereo to a bracket at the back or on either side. Determine the size of the bolts, then use a hand wrench to remove them. Some brackets won't require that you remove the bolts completely, but may just need you to loosen them sufficiently to slide the stereo out. There may be a trim "faceplate" over the stereo that pops off, revealing bolts in the face of the stereo instead of behind it. Unscrew these bolts and slide the stereo out. Remember that the stereo is still connected to the car with wires, so be careful not to rip any out as you remove the stereo from the console. If you are removing a stock head unit, there will likely be at least one plastic clip with a number of wires going into it that you will need to disconnect. There may be a second clip and an antennae cable as well in some cars. These few clips consolidate all the wiring required to connect the stereo to the car's power source, the antennae and each of the speakers. If you are removing an aftermarket stereo, there is a possibility that there will be no clip and the previous stereo was wired loosely. If that is the case, you may have to cut the wires in order to connect them to the new head unit. Do not pull the wires out of the clip. If you are able to purchase a harness adaptor for your new stereo, it will plug directly into the car's existing clip. Be careful when removing the wire harness clip from the back of the stereo. It may have a plastic button or tab holding it in place.

Children between the ages of 8 and 18 spend an average of 7.5 hours a day using electronics and media such as TV, cell phones, computers, and video games. The American Academy of Pediatrics (AAP) recommends that kids and teens should use media such as this for "no more than one or two hours per day." You can limit tech consumption by establishing a "curfew" for media devices, such as requiring them to be shut off before bedtime. Setting up scheduled times when your children are allowed to use media and technology, such as a "video game hour," will help establish boundaries for proper use. Have a small box or shelf for your child to put his or her cell phone in before they go outside. This will encourage them to be more mindful about where and when they use it, and will make it easier for you to make sure they're actually getting the quality outdoor time they need. You don't have to toss all your tech, but the American Academy of Pediatrics recommends that parents create "screen-free" zones at home by taking actions such as turning off the TV at mealtimes and making sure that children's bedrooms don't have computers, TVs, or video games in them. If your children know there are other options for recreation than media consumption, they will be more likely to take advantage of them. If you have a backyard, you may need to spruce it up a little to make it fun for your kids to play in. Clear away overgrown brush and any poisonous plants and keep the yard mowed. Things such as swing-sets and sandboxes provide hours of fun. If you live an urban area or don't have a yard, you still have options. find a safe, pleasant park or playground and make it a habit to take your kids there. You can even search the Internet for recommendations from people in your community. There are also online playground finders. Studies have show that adults who feel a sense of community with their neighbors are likely to spend more time outdoors for recreation and exercise, and this carries over to their children too. Parents who know their neighbors are also more likely to feel safe letting their children play outdoors. Getting to know your neighborhood can be particularly helpful if you don't have a suitable play area for your kids at your own home. In addition to the health benefits of outdoor play, allowing your kids to play at their friends' houses promotes social skills development, helps them learn teamwork, and relieves stress.
