Being sick is uncomfortable and your child may be worried or upset because of how he or she feels. Giving your child some extra attention and care may help. For example, you can:  Sit with your child. Read your child a book. Sing to your child. Hold your child’s hand. Hold your baby in your arms. A cough can get worse if your child is lying flat on his or her back. To keep your child’s head elevated, try putting a book or towel under the mattress of your baby’s crib or under the legs at the head of the crib or bed. You can also give your child an extra pillow or use a wedge pillow to help your child stay upright. Dry air can make a cough or sore throat feel worse. Try using a humidifier or cool-mist vaporizer to keep the air in your child’s room moist. This can help to reduce coughing, congestion, and discomfort.  Make sure to change the water in your humidifier frequently. Wash the humidifier according to the manufacturer's instructions to prevent mold from growing in it. Keep your home as quiet and peaceful as possible to make it easier for your child to rest. Stimulation from television or computers prevents sleep and your child needs as much rest as possible, so you may consider removing devices from your child’s bedroom or at least limiting your child’s use of devices. Your child may feel hot or cold depending on the illness, so adjusting the temperature in your home may help your child to feel more comfortable. It may be helpful to keep your home between 65 and 70 degrees, but you can also adjust this temperature if your child is too hot or too cold. For example, if your child is complaining that he or she is too cold, then turn up the heat a bit. If your child complains that he or she is hot, then turn on an air conditioner or fan.
