Tell me, my son started having a fever at night, he was fine during the day but had no appetite. He pooped an hour after I put a candle in, his temperature even went up, and he didn't sleep at all. I changed everything and woke him up, gave him ibuprofen with water because he keeps sucking on it but won't eat anything. He drank some water, did I do the right thing, thinking that the candle came out with poop? He got sick from it. It's strange that he has a fever, to say teeth, one just came out, the second is coming soon, only thought maybe for the first time so without symptoms. And now he's burning up all night,
