Diabetes and Your Child: Checking Blood Sugar

You’ve been told that your child has diabetes. This means that you must check his or her blood sugar level as advised by the healthcare provider. This is the only way to know if your child’s management plan is working. Your child’s healthcare team will teach you how to check your child’s blood sugar. You will learn how often to check and what the numbers mean for your child. This will help you keep your child’s blood sugar in a healthy range.

Using a blood glucose meter

Blood sugar level is measured with a blood glucose meter . A meter measures how much glucose is in your child’s blood. You’ll use a device called a lancet to get a tiny drop of blood. Blood is most often taken from a fingertip. But you may be able to test on the arm or the heel of the hand. The drop of blood is placed on a small strip that goes into the meter. The meter then gives a reading that tells you the level of your child’s blood sugar. There are several types of meters available. Your child’s healthcare provider will help you choose a meter that best suits your child’s needs.

Continuous glucose monitoring

Continuous glucose monitoring (CGM) may be an option for checking blood sugar levels. It tracks your child's blood sugar level throughout the day and night. This can help you and your child make better choices about food, physical activities, and taking medicines. It can also find trends and patterns that can help your child's healthcare provider better manage your child's diabetes. Ask your healthcare provider if CGM is right for your child.

Several CGM devices are available. They are approved by the FDA with a prescription from a healthcare provider. It includes a sensor, transmitter, and a receiver or monitor. The sensor is a small device placed under the skin. It will measure your child’s blood sugar several times a minute. A transmitter sends the information to a receiver. This may be a part of an insulin pump or a separate device.

Your child's blood sugar will still need to be checked a few times a day with a regular glucose meter to check for accuracy. The sensor under the skin needs to be replaced every 3 to 7 days.

Aim for target range

As often as possible, your child’s blood sugar should be in the target range. Target range is where his or her blood sugar level is healthiest. Aim to keep your child’s blood sugar in target range. This will help reduce the risk of health problems, including diabetic ketoacidosis (DKA) or low blood sugar (hypoglycemia). Your child’s healthcare provider will help you figure out what his or her target range should be. Fill in your child’s target range here:

  • Before a meal: Between ________________ and ________________

  • 2 hours after a meal: Between ________________  and ________________

  • Bedtime: Between ________________  and ________________ 

Why check blood sugar?

Your goal is to keep your child as healthy as possible by controlling blood sugar levels. Your healthcare team will work with you to set blood sugar target ranges for your child. They’ll also teach you how to check your child’s blood sugar. This will help you keep your child’s blood sugar levels in a healthy range.

Tracking your child’s readings

Keep a record of all your child’s blood sugar readings. You can use a “log book” to write down numbers. Or, many meters can store numbers that you can download to a computer. Keeping a record helps you see patterns, such as high numbers after certain foods or activities. Use your child’s log book to spot patterns and make adjustments to his or her management plan. This will help you keep your child’s blood sugar in his or her target range more often. Be sure to bring the log book to all appointments with your child’s healthcare provider. Smartphone apps are also available to record the blood sugar readings in a format you and your child's healthcare provider can down load at the next appointment.

If you like electronic record keeping, the American Diabetes Association (ADA) has a program called Diabetes 24/7. This online program provides tools to help monitor diabetes, including blood glucose levels. Your provider may also have an electronic medical record that offers the same type of tracking options.

Problem solving

You can use your child’s log to spot patterns and find answers to problems. For example, the log can help you see what tends to happen at a certain time of day, or when your child eats a certain food. Problem solving can be a “detective” game for you and your child. Together, you can find clues and figure out what they mean.

Checking blood sugar is part of life

Checking blood sugar should be part of your child’s daily routine. Make sure your child has a meter and supplies whenever he or she is away from home. To encourage your child to check regularly, make sure he or she knows the purpose of checking. It's part of the “detective” work that helps you and your child make decisions and solve problems.

Tips

To make finger sticks less painful:

  • Use the side of the finger.

  • Use a meter that requires less blood.

  • Use an adjustable lancing device.

  • Use a “fine” lancet.

  • Don’t clean the finger with alcohol—soap and water is fine. Be sure the finger is dry before getting the blood sample.

Make an agreement with your child

You, the diabetes educator, and your child can work out an agreement for blood sugar monitoring. It should include:

  • The times and situations when your child agrees to check his or her blood sugar.

  • What kind of log your child will keep.

  • A reward system for sticking to the agreement and being honest. Nonfood rewards are best. Never use skipping an insulin shot as a reward.

Encourage your child to do more

As your child gets older, he or she can take on more tasks. To do this, your child will need to learn with you about managing diabetes. If your child wants to do his or her own blood sugar checks, that’s great! But keep in mind that things may not work perfectly at first. That’s OK. You can both keep trying. Ask your provider about support groups for children or age-appropriate diabetes camps and programs.

 

Sometimes, your child will have high or low numbers. You may not know right away why this happened. Don’t get upset if you see numbers that are out of range. And try not to judge your child’s behavior based on these numbers. Many things can affect blood sugar level, including emotions, such as excitement. So don’t punish your child or get upset at high or low readings. Your child needs to trust that he or she can show you any number. If you are having trouble keeping your child’s blood sugar in target range, contact your child’s healthcare provider. He or she can help you adjust your child’s plan as needed.
