If your child has a runny nose, a sore throat, a cough and congestion, she might have the common cold, according to Children's Hospital Boston in the article "Upper Respiratory Infection." There is no cure for the common cold, and the symptoms usually do not require a doctor's care. If it's OK with your child's pediatrician, you can try home remedies to help soothe your child's symptoms. If symptoms worsen or last longer than two weeks, seek further care.
Spray a saline spray into the sinuses to help clear out the nasal passages, BabyCenter recommends. You can purchase saline nose drops at the drugstore or grocery store. Spray once into each nostril, then instruct your child to carefully blow his nose.
Make your child a bowl of chicken soup. Chicken soup helps speed up mucus movement, which helps relieve congestion. Additionally, chicken soup slows neutrophil movement, which prevents inflammation in the body.
Place a cool-mist humidifier in your child's bedroom to help relieve a cough and nasal congestion, according to Children's Hospital Boston. A cool mist humidifier should be cleaned several times a week to prevent growth of mold.
Prop your child's head up with pillows to relieve congestion overnight. If your child is up all night coughing, adding an extra pillow might help her get a good night's sleep.
Prepare a saltwater gargle for your child. Mix 1/2 tsp. salt in an 8-ounce glass of warm water. Instruct your child to place a mouthful of the liquid in the back of her throat and gargle for several seconds. Instruct your child to spit the water out--do not allow your child to swallow the water.
