Cold and flu season is here and parents everywhere are waging war against sore throats, stuffy noses and high fevers. But, what's a mama to do when sickness has breached the walls of her home and taken up residence in the form of a chicken soup-downing kiddo on the couch?

Hope is not lost: We reached out to experts for their best tips on protecting yourself—and limiting the spread of colds or the flu. In addition to washing (and washing and washing) those hands and talking to your healthcare provider about the flu shot, the pros had some other often-overlooked recommendations for how to stay healthy in a germ-y home.

1. Boost immunity with breakfast

The war on the common cold can start at the breakfast table. Registered dietitian Susan Stalte says families should cut the processed foods and add more nutrient-dense foods especially at breakfast. "Morning protein is important for fullness, but it also helps with tissue repair and a general immune-system boost," says Stalte.

She says parents should opt for whole protein sources such as meat, fish, dairy, eggs, beans, tofu or nuts to add some immune-boosting protein power to breakfast. Then aim to round it out—at least throughout the rest of the day. "A nutritionally balanced diet is best for cold prevention as each nutrient plays a different key role in overall wellness," says Stalte.

2. If you feel a cold coming on, turn to the vitamin C + zinc team

Some studies suggest high doses of vitamin C or zinc can limit the duration of an upper respiratory infection or cold . It's not 100% effective, but the risk of toxicity is minimal —so it's worth a shot even if there's a small benefit, says Dr. Gonzalo Bearman, professor of medicine and chair of the Division of Infectious Diseases in the Virginia Commonwealth University School of Medicine.

And it's not too late if you're already sick. Dr. Celine Thum, Medical Director at ParaDocs Worldwide, says the combo of vitamin C and zinc can decrease the duration of symptoms even after a cold starts to set in. "When you start to feel a little bit sick and start to feel that scratchy throat and think, 'Maybe I am coming down with something,' go ahead and take vitamin C," says Thum, who recommends lozenges.

3. If you're feeling adventurous, try some seaweed

If vitamin C-rich foods such as peppers, brussels sprouts and broccoli are too tame for your taste, seaweed is a great source of C and other immune boosting vitamins, says Davida Mitchell, L.Ac., Doctor of Acupuncture and Oriental Medicine.

"Vitamins A and D, both fat-soluble vitamins, are imperative to immune health, but they are much more effective for preventing and reversing colds and flus when taken together," she explains.

Just don't go overboard with devouring seaweed: As the Globe and Mail notes, doctors have reported rare but serious cases of excess iodine and heavy metal toxicity in patients who consumed more than 10 grams or so of kelp per day. Mitchell says it helps to source your seaweed as sustainably and locally as possible.

4. Stay hydrated

Seaweed may be having a moment right now and veggies are obviously awesome for the whole family, but Dr. Bearman cautions there is no menu item with the antiviral properties to can stop a cold or flu from happening altogether.

It does help, however, to down a few glasses of water—at least when it comes to helping the body respond to the stress of illness. "Adequate hydration is important for overall homeostasis," says Dr. Bearman. "It does allow the body to better respond to any sort of stressor."

5. Get as much sleep as possible

Studies show that being well rested goes a long way toward fending off the flu or colds —with one report finding people who slept an average of less than six hours per night were 4.2 times more likely to catch a cold than fellow test subjects who logged more than seven hours of sleep.

"Short sleep was more important than any other factor in predicting subjects' likelihood of catching cold," said the study's lead author Aric Prather, Ph.D., in a media release . "It didn't matter how old people were, their stress levels, their race, education or income. It didn't matter if they were a smoker. With all those things taken into account, statistically sleep still carried the day."

Of course, if you want to avoid getting a cold or the flu in the coming months, now is the best time to talk to your health care provider for recommendations on the flu shot and other preventative measures. And of course, hand washing is a huge factor in preventing cold and flu from spreading.
