<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, thank you so much! My question is this: if a 1 year old baby has 40.3 high fever. How long can we wait till we should consult a doctor firsthand? Meanwhile, we are trying to bring the fever down by giving paracetamol every 4 hours and wiping her with wet cloth to cool down. By the way, the website said this is for free  <response>: Hi, Im Chat Doctor. 3 Celsius temperature in an 1-year-old child is very high, do tepid sponging of whole body and do consult a doctor urgently, because such a higher fever can cause convulsions and permanent damage to brain. So regardless of babies condition you need to consult your health care provider or emergency. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Take care, act urgently. Thanks.
