Prevent dehydration. Encourage your child to drink extra fluids or suck on flavored ice pops, such as Popsicles. Let your baby breast-feed more often or give your baby extra bottles. Liquids may help thin the mucus and also reduce fever (if present). But don't force your child to take fluids, which may cause your child to vomit.
Let your child rest. Unless you see signs of dehydration, do not awaken your child during naps or at night to take fluids.
Keep your child away from smoke and fumes. This includes cigarette smoke, smoke from wood-burning stoves, and fumes from gas, oil, or kerosene heaters. These irritate the breathing tubes and slow healing.
Place extra pillows under the upper half of an older child's body, or raise the head of the bed by putting wood blocks under the bed frame.
