As he is experiencing severe lethargy, pale skin, and is not drinking well alongside his fever and cough, it is very important that he is evaluated by a doctor immediately. Please take him to the nearest emergency room or pediatric urgent care right away. These symptoms can be signs of severe dehydration or a more serious infection that needs prompt professional care. While on the way, try to keep him comfortable, but do not give any new medications without a doctor's advice.

It is very common for babies to develop a mild fever after their 10-week immunizations, but this typically resolves within 24 to 48 hours. Since the fever is returning on the third night despite giving Crocin (paracetamol), it is important to have your baby evaluated by a pediatrician. While it could still be a lingering vaccine reaction, a fever lasting three days in a two-month-old warrants a professional checkup to rule out other infections. Please ensure your baby stays hydrated and dressed in light clothing. If you notice extreme sleepiness, poor feeding, or difficulty breathing, please seek medical care immediately.

At two years old, keeping her hydrated is key. Offer frequent sips of water, warm broths, or milk. For the cough and cold, saline nasal drops can ease her congestion, and plenty of rest will help her body heal. Since the fever has temporarily subsided, please continue to monitor her closely. If the fever returns and lasts more than three days, or if she has trouble breathing, is unusually sleepy, or refuses fluids, please have her evaluated by a pediatrician.

Crocin (paracetamol) can take up to two hours to show its full effect, so it may just need a little more time. For your safety, always wait 4 to 6 hours between doses of paracetamol, and never exceed 4,000 mg in 24 hours. To help you feel more comfortable right now, try lukewarm sponge baths, stay well-hydrated, and rest. If the fever remains high after 4 hours, consult a healthcare provider about alternative options like ibuprofen. Please seek immediate medical care if you develop breathing difficulties, confusion, or a stiff neck.

While mild fevers are common after vaccination, they typically resolve within two to three days. Since her fever started a few days after her vaccination and has lasted for three days despite taking Crocin (paracetamol), it is best to be cautious. This could be due to an unrelated infection, including COVID-19. I highly recommend consulting a doctor and getting her tested for COVID-19. In the meantime, please ensure she rests, stays well-hydrated, and remains isolated from others to keep everyone safe.

Give Crocin syrup (paracetamol) for the fever every 4 to 6 hours as needed, based on your child's weight. Nasoclear (saline drops) is very safe and can be used anytime to clear a stuffy nose. For S-Mucolite and Allegra (fexofenadine), please follow your pediatrician's specific daily schedule. To prevent tummy upset, wait about 15 minutes between giving different syrups. Please check with your doctor for the exact dosages tailored to your child's weight.
