I'm so worried about my baby. He has strep throat. He has had a fever since yesterday. Yesterday it got to 103 and I took him to the dr which is when we found out he had strep. He's barely eating and drinking very little. I took him back to the dr today bc he won't take his antibiotics and they gave him a shot. He has a 101 fever now so I'm gonna try some Tylenol to try to break it. Any suggestions?
