In one sentence, describe what the following article is about:

You have a right to carry everything your child needs for their diabetes. That includes insulin, insulin pumps, medications, syringes, lancets, and even liquid carbohydrates in greater quantities than 3.4 fluid ounces (100mL). Your items will need to go through the x-ray machine, which will not harm the insulin or the glucose meters. Getting through security will go much quicker if you include the prescription labels with medications and have them ready in a clear bag. While this card is not required, it will help the process go more smoothly. Basically, you print the card off and write on it that your child has diabetes. Then you hand it to the TSA agents. Many domestic flights no longer offer in-flight meals. If one is available, ask for a diabetic option for your child. If they're not available, bring a healthy meal with you for your child to eat if the flight is long enough that they will need to eat. Whether you bring a meal or not, be sure to have snacks and/or fast-acting glucose, such as glucose tablets, on hand in case your child's blood sugar dips. If you're driving or taking the bus, check the route ahead of time for food stops. If you expect that your child will need to go to the restroom to check their blood sugar during the flight, ask for an aisle seat. This will allow them to quickly get to the restroom without disturbing other passengers. On long flights, check your child's blood sugar every 2 hours. New schedules and jet lag can mess with your child's blood sugar levels, as well as make it difficult for them to determine when their sugars are low. Take time after you get off the flight to check their blood sugar levels and adjust as needed. Sitting in the car or plane too long can lead to high blood sugar levels. If you're in the car, try to stop every 1-2 hours, and add some stops that allow your kid to run around. For instance, try stopping somewhere with a playground when you're in the car. On a plane, have your child at least get up and go to the bathroom every hour. Between flights, give them a chance to stretch their legs.

Summary:
Know your child's rights before flying. Bring a TSA Disability Notification Card. Check ahead of time for in-flight meals and snacks. Request an aisle seat for your child. Check your child's blood sugar right after landing. Take exercise breaks to control your child's blood sugar.
