If the nose is blocked up, your child will not be able to drink from a bottle or breast-feed. Suction alone cannot remove dry secretions. Place three drops of warm water or saline in each nostril. After about 1 minute, use a soft rubber suction bulb to suck out the mucus. Encourage your child to drink enough fluids.
Breathing becomes labored or difficult.
Any fever lasts more than 3 days.
