While the common cold is generally mild and self-limiting, it is important to monitor your baby’s symptoms and provide comfort measures such as saline nasal drops and a humidifier to ease congestion. Ensure that your baby stays hydrated and gets plenty of rest to help them recover.
Influenza
Influenza, or the flu, is another respiratory illness that infants are susceptible to. It is caused by the influenza virus and can lead to more severe symptoms compared to the common cold. Infants with the flu may experience high fever, cough, sore throat, body aches, and fatigue. It is crucial to consult a healthcare professional if your baby exhibits flu symptoms, as treatment with antiviral medication may be necessary. Additionally, practicing good hygiene, such as frequent handwashing and ensuring everyone in the household receives the annual flu vaccine, can help prevent the spread of the flu to infants.
Bronchiolitis
Bronchiolitis is a respiratory illness primarily caused by the respiratory syncytial virus (RSV). It commonly affects infants and young children. Bronchiolitis is characterized by inflammation and congestion in the small airways of the lungs, causing symptoms like nasal congestion, coughing, wheezing, and difficulty breathing. In severe cases, infants may require hospitalization for supportive care. To reduce the risk of bronchiolitis, practicing good hand hygiene and avoiding close contact with individuals who have respiratory infections, especially during RSV season, is important.
Respiratory syncytial virus (RSV)
RSV is a common respiratory infection in infants and young children. It is highly contagious and spreads through droplets from coughing and sneezing. RSV typically causes symptoms similar to a common cold, such as runny or stuffy nose, coughing, and mild fever. However, in some cases, RSV can lead to more severe respiratory distress in infants, especially those with underlying health conditions. It is crucial to seek medical attention if your baby shows signs of difficulty breathing or if their symptoms worsen over time.
Pneumonia
Pneumonia is a serious respiratory infection that can affect infants as well. It is usually caused by bacteria or viruses and results in inflammation and infection in the lungs. Infants with pneumonia may exhibit symptoms such as fever, rapid breathing, cough, chest pain, and decreased appetite. Prompt medical attention is necessary if your baby shows signs of pneumonia, as it may require antibiotic treatment. Prevention measures, such as practicing good hand hygiene and ensuring appropriate immunizations, can help reduce the risk of pneumonia in infants.
Gastrointestinal illnesses
Gastroenteritis
Gastroenteritis, commonly known as the stomach flu, is an inflammation of the stomach and intestines. It is often caused by viruses, such as rotavirus or norovirus, and can lead to symptoms like vomiting, diarrhea, stomach cramps, and fever. Infants can easily contract gastroenteritis through contaminated food, water, or close contact with infected individuals. It is essential to ensure your baby receives adequate fluids to prevent dehydration and consult a healthcare professional if their symptoms worsen or persist.
Diarrhea
Diarrhea is a common digestive issue in infants, characterized by frequent, loose, and watery bowel movements. It can be caused by various factors, such as viral or bacterial infections, food intolerance, or changes in diet. Diarrhea can lead to dehydration, so it is important to monitor your baby’s fluid intake and provide oral rehydration solutions if necessary. If your baby’s diarrhea is severe, lasts longer than a few days, or is accompanied by other concerning symptoms, seek medical advice.
Vomiting
Vomiting, often accompanied by nausea, is another gastrointestinal symptom frequently seen in infants. It can result from various causes, including viral infections, food poisoning, or underlying medical conditions. The most important thing when your baby is vomiting is to prevent dehydration by providing small, frequent sips of clear fluids and avoiding solid foods until vomiting subsides. If vomiting persists or is severe, consult a healthcare professional for further evaluation and guidance.
Reflux
Reflux, also known as gastroesophageal reflux, occurs when stomach contents flow backward into the esophagus. It is common in infants and often considered a normal part of their development. Symptoms of reflux include frequent spitting up or regurgitation, irritability during or after feeds, and poor weight gain. Most cases of reflux improve without treatment, but if your baby experiences severe reflux symptoms or shows signs of distress, it is important to consult a healthcare provider for appropriate management strategies.
Constipation
Constipation is a condition characterized by infrequent and difficult bowel movements. It can occur in infants due to various reasons like formula changes, inadequate fluid intake, or introduction of solid foods. Signs of constipation in infants include hard, dry stools, discomfort, and straining during bowel movements. To help alleviate constipation, providing adequate fluids, ensuring a balanced diet, and incorporating high-fiber foods can be beneficial. If constipation persists or is accompanied by other concerning symptoms, consult a healthcare professional for guidance.
Skin conditions
Diaper rash
Diaper rash is a common skin condition that affects infants who wear diapers. It is typically caused by prolonged skin exposure to moisture, irritation from urine or stool, or the presence of a fungal or bacterial infection. Diaper rash appears as red, inflamed skin in the diaper area, often accompanied by small bumps or blisters. To prevent and treat diaper rash, it is important to keep the diaper area clean and dry, use appropriate diaper creams or ointments, and change diapers frequently. If the rash worsens or is accompanied by signs of infection, consult a healthcare professional.
Eczema

Cradle cap
Cradle cap, medically known as seborrheic dermatitis, is a common scalp condition in infants. It appears as yellowish, greasy scales or flakes on the scalp and may also affect other areas like the face or diaper area. While the exact cause of cradle cap is unknown, it is believed to be related to overactive sebaceous glands on the scalp. Cradle cap typically resolves on its own without treatment, but gentle scalp massage, regular washing with mild shampoo, and brushing with a soft brush or comb can help remove the scales.
Heat rash
Heat rash, also called prickly heat or miliaria, occurs when sweat glands become blocked, trapping perspiration beneath the skin. It commonly affects infants in hot and humid environments, leading to small red bumps or blisters on the skin. To prevent and alleviate heat rash, it is important to dress your baby in lightweight and breathable clothing, keep the environment cool, and ensure proper air circulation. Avoid excessive heat and humidity, as well as tight-fitting or synthetic clothing that may trap heat.
Milia
Milia are tiny white bumps that often appear on a baby’s nose, cheeks, or chin. These tiny cysts are caused by trapped keratin, a protein found in the skin. Milia are harmless and typically resolve on their own within a few weeks or months. It is important not to squeeze or pick at the milia to avoid potential infection or scarring. Keeping your baby’s skin clean and moisturized can help prevent milia from forming or worsening.
Fever-related illnesses
Viral fever
A viral fever refers to an increase in body temperature caused by a viral infection. Infants can develop a fever in response to various viruses, including those causing respiratory or gastrointestinal infections. Fever is the body’s natural response to fight off infection. It is crucial to monitor your baby’s temperature using a reliable thermometer and consult a healthcare professional if the fever is persistent, high, or accompanied by other concerning symptoms.

Symptoms of eyelid inflammation may include redness, swelling, itching, crusting of the eyelids, and watery or sticky eyes. Regular eyelid hygiene, including gentle cleaning with warm water and mild baby shampoo, can help alleviate symptoms. If your baby’s eyelid inflammation persists or worsens, consult a healthcare professional for further evaluation and guidance.
Neonatal jaundice
Physiological jaundice
Physiological jaundice is a common condition in newborns, characterized by the yellowing of the skin and eyes. It occurs due to the temporary buildup of bilirubin, a yellow pigment produced when red blood cells are broken down. Physiological jaundice is usually harmless and resolves on its own within a few weeks. However, it is important to monitor and manage jaundice, as high levels of bilirubin can be harmful. Regular medical check-ups and monitoring of bilirubin levels are essential to ensure appropriate management.
Breast milk jaundice
Breast milk jaundice is a type of jaundice that occurs in some breastfed infants, usually after the first week of life. It is believed to be caused by certain substances present in breast milk that inhibit the breakdown of bilirubin. Breast milk jaundice is usually benign and does not require treatment unless the levels of bilirubin become excessively high or the baby shows signs of complications. Monitoring the baby’s bilirubin levels and ensuring adequate hydration and feeding is important in managing breast milk jaundice.
Breastfeeding failure jaundice
Breastfeeding failure jaundice can occur when a baby does not receive enough breast milk due to breastfeeding difficulties or inadequate milk production. The insufficient intake of breast milk can lead to dehydration and reduced elimination of bilirubin, resulting in elevated levels and prolonged jaundice. It is important to seek guidance from healthcare professionals if breastfeeding difficulties arise and to ensure that your baby is effectively nursing to prevent or manage breastfeeding failure jaundice.
Pathological jaundice
Pathological jaundice refers to jaundice that occurs due to underlying medical conditions, such as blood disorders or infections, that affect the normal breakdown or elimination of bilirubin. Pathological jaundice is typically more severe and requires immediate medical attention for diagnosis and appropriate treatment. It is crucial to consult a healthcare professional if your baby exhibits prolonged or worsening jaundice, as prompt intervention is necessary to address the underlying cause.
Urinary and kidney infections
Urinary tract infection (UTI)
Urinary tract infections (UTIs) can occur in infants, although they are less common compared to older children. UTIs in infants are usually caused by bacteria entering the urinary tract through the urethra. Symptoms of a UTI in infants can be subtle but may include fever, irritability, poor feeding, vomiting, or foul-smelling urine. It is important to seek medical evaluation if your baby develops a fever, especially if there are other signs suggesting a possible UTI, as prompt diagnosis and treatment are essential to prevent complications.
Kidney infection (pyelonephritis)
Pyelonephritis is a kidney infection that occurs when a urinary tract infection spreads to the kidneys. While less common in infants, it can lead to more severe symptoms and potential complications. Typical signs of pyelonephritis in infants may include high fever, irritability, poor feeding, vomiting, abdominal pain, or abnormal urination. Prompt medical attention is necessary if you suspect your baby has a kidney infection, as it often requires antibiotic treatment and close monitoring to prevent further complications.
Bladder infection (cystitis)
Cystitis refers to an infection or inflammation of the bladder. Although less common in infants, it can occur and may cause symptoms such as fever, irritability, poor feeding, foul-smelling urine, or discomfort during urination. It is important to seek medical evaluation if you suspect your baby has a bladder infection, as early diagnosis and appropriate treatment are essential to prevent complications and promote healing.
Vaccine-preventable illnesses
Whooping cough (pertussis)
Whooping cough, or pertussis, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. It can cause severe coughing fits, difficulty breathing, and a characteristic “whooping” sound during inhalation after a coughing episode. Whooping cough can be particularly dangerous for infants, as they are at an increased risk of complications and severe illness. Immunization of both infants and close contacts through the pertussis vaccine is crucial for preventing the spread of this potentially life-threatening illness.
