The desire to make our kids feel better when they are sick is the reason it's so frustrating that cold medicines don't work. I have some patients who are convinced cold medicine helps their children. If the child is over age six, I don't mind parents using medication because the risks are low. That being said, if they don't see relief after a few doses, it's unlikely to be helpful. In children less than six, you are mostly stuck with fever and pain control, a vaporizer and hydration to relieve nasal congestion.
Nasal congestion is very difficult to treat in young children and kids less than four are not good a blowing their noses. Some parents find that nasal washes are helpful, but like you, many also find that their children hate anything getting near their nose. A warm, wet washcloth sometimes helps a stuffy nose, though it won't do anything to reduce the internal congestion.
For thumb suckers, colds are especially difficult to deal with. My eldest sucked her thumb until she was six and anytime she got a cold we had rough nights because she couldn't sleep.
