Read this post to know about various causes of sore throat in newborns, how to treat it, and the preventive measures for the condition.
What Causes Sore Throat In Babies?
A sore throat could be a symptom of various conditions. Here are the most common ones:
- Viral infections are the leading cause of a sore throat in babies (2). A plethora of viruses can cause it, but the common ones are the cold virus, adenovirusiXViruses that cause respiratory illnesses. , influenza (flu) virus, coxsackievirusiXA virus that is the main cause of hand, foot, and mouth disease. , and herpesiXRash or blisters on the body caused by a virus that can spread from a person with a cold sore to a baby. virus (3) (4) (5). Some viral infections that could cause a sore throat are the common cold, flu, tonsillitis, hand, foot, and mouth disease, bronchitis, or laryngitis.
- Bacterial infections are caused by Streptococcus (strep throat) and Corynebacterium diphtheriae (diphtheria) (6) (7). Both lead to a severe sore throat. Strep throat is one condition that can cause a sore throat due to bacterial infection. Further more, the migration of the strep throat-causing bacteria to the lungs may lead to the development of pneumonia.
- Allergies caused by inhalation of potential allergens such as pollens, particles of wheat flour, or molds, could lead to congestion and an itchy and sore throat. An allergy, where the sore throat is quite common, is called allergic rhinitisiXAn inflammation of the inner lining of the nose caused by allergens. (8).
- In gastroesophageal reflux disease, the baby’s poorly developed lower esophageal sphincteriXA band of muscle present at the place where the esophagus meets the stomach. does not close properly. The stomach acids and other contents flow upwards as far as the throat and cause constant irritation to the throat, leading to chronic sore throat (9).
- Smoke and pollution, such as suspended air particles, affect the baby’s delicate throat lining and eventually cause a sore throat.
- Adenoids and enlarged tonsils are referred to as tonsillitis which may lead to sore throat accompanied with trouble in swallowing or an inner ear infection among children (10).
The sore throat in infants could easily be spotted by a parent.
Excessive mucus discharge and red blisters around the mouth and parts of the body indicate the need for prompt medical intervention.
What Are The Symptoms Of A Sore Throat?
- Redness on the inside of the throat: Every time the baby opens the mouth to eat or cry, you notice a dark-red hue at the back of the mouth where the throat begins.
- Difficulty swallowing: The baby has trouble taking solid food or breastmilk. There is a sudden aversion towards eating, and when the baby is hungry, they stop eating midway due to the pain while swallowing.
A mother of a baby girl, Karen details in her blog how her daughter refused to feed after she was diagnosed with a sore throat due to an infection in her ears. She says, “That morning in the doctor’s office was the last time she nursed. I don’t know if it was the stuffy nose, ear pain and pressure, or a sore throat, but from that morning on she refused to nurse at all. She would arch her back, push me away, and scream.
She adds, “We’ve settled on a medicine cup as the most effective way of getting any fluids into her, which is a bit of a slow process and certainly not one she can do herself as she could if she would take to a sippy cup or bottle. But she has shown no interest in nursing again. She continues to strenuously resist even being in a nursing position. She gets upset if I even begin to lift my shirt when she’s on my lap. So I’m accepting that what I hoped would be a nursing strike is probably going to be a sudden weaning (i).”

Pus is made of white blood cells that defend the body against pathogensiXOrganisms like bacteria, fungi, and virus that causes various infections and diseases. . And, the presence of pus indicates an infection.
- Swollen neck: Inflammation is noticed from the outside, as the baby’s lymph nodesiXThe nodes present at different locations in the body as a part of the lymphatic system for filtering the substances passing through and manufacturing lymphocytes. are swollen.
- Hoarse voice: Older infants who can speak a bit may experience hoarseness and speak in a muffled tone due to inflammation of the tonsils.
- Cough: The irritation caused by a sore throat can make a baby cough repeatedly.
Sore throat is usually a benign condition, but if the cause is bacterial, then can lead to severe complications. If you have a young baby or toddler or if your child has fever or other complaints along with the sore throat, then speak to your doctor.
Home Remedies For Sore Throat In Babies
Home remedies could be a good way to alleviate the discomfort caused by a sore throat. Here is what you can do to make the baby feel better.
- Give sips of warm water. The American Academy of Pediatrics (AAP) recommends this home remedy for babies aged three months and older (13). Heat drinking water until it is warm enough to swallow comfortably. Give 5-15ml of water about four times a day as it relieves itchy, sore throat symptoms, and inflammation.
- Clean the baby’s nose if they have a runny nose and ensure that you clean the baby’s nose frequently. This is important as the baby will not be able to do that themselves (12). You may also use suction via a bulb syringe to clean the baby’s nose.
- Give a warm broth made of chicken or vegetables, to infants older than six months. Cook vegetable or chicken broth, cool it until it is warm, and then feed to the baby (14).
- Provide adequate fluids and breastfeed more than normal to babies below six months to soothe the throat irritation. Babies older than six months should be given a lot of fluids to calm the soreness. Feed diluted purees, broths, and stocks. Do not give fruit juice as it is not helpful and offers no nutritional benefits (15).
- Frozen liquids or cold foods like popsicle or ice cream could be given to a baby (older than six months) to soothe a sore throat (16).
- Install a humidifier in the infant’s room to maintain ideal water vapor levels. Dry air can irritate the baby’s sore throat, and optimum humidity relieves irritation. Use a cool-mist humidifier and not hot-water/steam vaporizers as they increase the risk of nasal burns (16).
Pediatric experts recommend against the usage of infant throat syrups and lozenges since they do not provide many benefits (11).

How To Treat Sore Throat In Infants?
A sore throat usually does not require treatment and cures by itself (17). A doctor may, however, prescribe medications to treat the underlying condition.

Wash your hands before holding the baby and handling their personal items. If a family member, including a baby’s sibling, has a cold or fever, then keep the baby away from that individual till the person cures. These steps help in minimizing the risk of an infection that could eventually lead to a sore throat.
- Be watchful of allergies: Stay alert to any symptoms that could point to allergies. Timely detection of allergies helps you shield the baby from the allergen that could cause a sore throat. According to the National Center for Health Statistics 2021 data, seasonal allergy affected 10.4% of children between zero and five years. On the other hand, food allergy affected 4.4% of children in that age group.
- Keep the air around the baby clean: Dust, smoke, and other airborne pollutants can lead to a sore throat. Close the windows in the house when it is dusty outside. Avoid taking a newborn to places where the air is polluted with automobile exhaust.
A sore throat could be a source of misery for an infant, but it is also a condition that is easily preventable. If the baby gets a sore throat, easy home remedies can help them feel better.
