What can I give my 4-year-old child to relieve a sore throat?

For a 4-year-old child with a sore throat, you can give them Tylenol to help relieve the pain. Encourage them to drink plenty of fluids according to their preferences. If their nose is congested or running, you can use a saline solution like Hydrasense or Sinus Rinse as needed throughout the day. Monitor their condition and if they are eating, even if less than usual, seem to be in a good mood overall, and are wetting and soiling their diapers, just keep an eye on them.
