Still fever

I just fed med to san san at 12am. She is still having high fever at 39.6 I am thinking if i should use the stronger fever med now. Or i should wait another hour. So that in between, the gap is not that big and i can fall back to the other fever med when the fever didnt go down. One is 4 hours interval and the stronger one is 6 hours interval.maybe i will feed at 1am if temp still as high, and at 4am feed another type. Will have to set alarm to wake up at 4am. I am very used to sleeping late and sleeping very little. I think the sense of responsibilty of being a mother, can overcome alot of things.very naturally u will do alot of things which u never thought u will be able to do, and the sense of duty is very strong.i can dun sleep for a few days if i have to do so, but i cannot do it for a long time. Age is catching up also, so i dont have that much energy.hope tomolo san san will be better. Recently she keep falling sick, and she has lost alot of weight already. Her round face has become pointed.
