Girls, how long does paracetamol take to work after? I lit a candle, the baby woke up, he ran and jumped for 2 hours, then lay down again. I thought it might rise again. I checked and it was already 37.6. After 5 minutes, I see sweat started and the temp normalized. Is this action of paracetamol not clear to you? Or maybe it's already normalizing the condition ? We've been sick for five days now. For four days we haven't taken any fever reducers.
