Breastfeed your baby if possible, as long as possible. Breast milk provides your baby with antibodies, which are important for fighting infection and strengthening the immune system.
Keep your children far away from secondhand smoke, which can cause colds as well as other serious health problems.
Make sure everyone in the household washes their hands thoroughly and frequently, especially after blowing their noses. If small children are unable to wash their own hands, do it for them. Use plenty of soap and water, and dry thoroughly.
Be sure kids get the sleep they need to stay healthy. Most children under age five need to sleep for 11 hours or more per day.
Encourage kids to drink plenty of water and round out their plate with colorful servings of fruits and veggies to help their immune system work properly.
