mild fever

Tiffany

so my 4month had his second round of shots today. His doctor said to watch out for fever. So far he doesn't really have one at 99.0 and i was told that once or if his fever reaches 100.2 to give him Tylenol. so far he's cranky n tired(all understandably so) but i got back to realize that the doctor never said how much to give him for his weight(14lbs 10.5oz) n the hospital hotline is not operational. so any advice
