If your child has a fever, it is important to consider certain signs that may indicate a need to see a doctor. Some general signs to look out for include a high fever lasting more than 24-48 hours in children under 2 years old, fevers lasting more than 3 days in children over 2 years old, rash or spots on the skin, inability to drink fluids, repeated vomiting or diarrhea, stiffness in the neck, a history of epilepsy or compromised immune function. In cases like these, it would be recommended to consult a doctor. It is also advisable to use fever-reducing medication like Tylenol, avoid using alcohol or ice for sponging or baths, dress in light clothing, keep the room temperature at around 20°C, and drink plenty of fluids to prevent dehydration.
