My three-month-old baby has symptoms of a cold (fatigue, congestion, irritability). When should I go see a doctor?

You should go and consult a doctor if your three-month-old baby is showing symptoms of a cold such as fatigue, congestion, and irritability. Keep an eye on their temperature and if it goes above 38 degrees Celsius, they may have a fever. Make sure they are drinking normally and wetting their diapers regularly. If the baby seems lethargic, extremely tired, lacks energy, or is not drinking enough, it may be time to seek medical advice. Additionally, if their temperature stays above 38 for more than 24 hours, or exceeds 39.5, or if they have difficulty breathing, it is recommended to see a doctor.
