We are right in the middle of Flu season and unfortunately it is hitting a lot of people this year.  Usually the flu just has to run it's course but there are a few things you can do to help relieve the symptoms.  Please consult your doctor with these ideas to make sure they are appropriate for your child.  Some children with special respiratory concerns, allergies, or health issues should be taken into consideration regarding ideas and doctor intervention is highly suggested.

First, make sure your child is getting plenty of fluids.  One of the biggest problems that accompanies flu is dehydration.  Encourage as many fluids as are reasonable and possible.  Respiratory secretions thicken up with dehydration as well.  Some fluids that may be most helpful are those which include electrolytes.  Gatorade or Pedialyte are examples.  Water is fine but it doesn't have the electrolytes that are helpful for the body to maintain hydration.  Milk may cause more secretions, so avoid it if possible.

Second, a humidifier may be helpful as well.  Make sure it is a cool mist humidifier, not a warm mist.  Cool mist helps reduce inflammation in the respiratory pathway and often opens the airway better.

Third, follow a doctor's directions on medication for discomfort.  Children's Tylenol or Children's Ibuprophen are the most common medications used to reduce fever and discomfort, but don't give any without consulting a physician and obtaining a correct dose.

Forth, plenty of rest.  The body heals better during rest periods.  Some activity is important to prevent secretions from pooling in the lungs, but don't forget to rest in order to heal.  To help with lung movement, blowing bubbles or blowing up a balloon could be helpful to expand the lungs.  This may cause coughing.  Some coughing is okay if it helps to clear the lungs, but if it is a distressing cough, go to the doctor.  Follow doctor instructions if any coughing causes distress or respiratory difficulty.

Fifth, monitor for fever.  Fevers are the body's way of fighting disease so some fever should be expected.  However, if the fever reaches 104 degrees consult a doctor.  I like to say here, go by how you feel.  If a lower fever has you concerned, by all means, call a doctor.  Also, if a fever lasts longer than a day or two, consult a doctor.

Sixth, to prevent spread of the flu, use good hand washing.  If possible, keep affected person away from others.  I know, this can be difficult to do.

Good luck, and call or see a doctor for any other help.
