Answer: More important than the fever itself is how your child feels overall. If she's eating, sleeping, and playing well, there is nothing much to worry. However if fever persists along with other symptoms like vomiting, loose motion, irritable nature, loss of appetite, lethargy etc then following suggestions might be of your help -
Try removing layers of clothing, giving her a lukewarm tub or sponge bath, or letting her rest in a cool (not cold) room. Prevent dehydration by giving liquids frequently.
If these steps don't bring relief, call your baby's doctor and ask fr medicine. Be sure to ask what dosage is appropriate – the safe amount is based on your baby's weight, which changes frequently. Make sure never to give more than the recommended dosage at the appropriate intervals. My doctor had recommended another medicine i.e., T98 for my child, that helped.
