What is the best remedy for 2 years old when they got flu? I don't want to bring to doctor yet and get some medicine.

I usually do the following for my 18 month old: A) give him a hot bath. The steam will help open up his airways B) use saline drops and a nasal syringe bulb to clear his nose C) rub a baby-safe vapor rub in his chest, back and neck D) make sure he has lots of fluids E) rest always helps :)
