My daughter temperature is between 38.3 and 39.5. it has now been stabled at 39 what else can i do to bring down her temperature and at what stage should i just go an admit her?

Admit ?????: You have not provided any significant details or reason for a hospitalization.Kids are admitted when they have need for services that cannot be provided at home, like IV fluids or IV antibiotics. If the kid is having difficulty taking fluids, doesn't pee at least once every 8 hrs or is laying around inactive take her in to be evaluated.The docs will decide when/if any hospital based care is needed

Best to not lower it: Your daughter probably has a viral infection. Fever is the key mechanism our immune system uses to fight infection; by lowering fever you will sabotage her immune system and prolong the infection! 39 is not dangerous (if it gets to 40 you might want to lower it a bit). Make sure she is well-hydrated. Unless she is really out-of-it no need to worry (or admit her). See https://tinyurl.com/y7a84ph8
