Hello girls, we've had a fever for two days now and she coughs up phlegm. I gave her amoxicillin, the doctor said that and also watery stool and frequent bowel movements. Honestly, I'm afraid to go back to the doctor again. They will probably give him injections there. It's definitely not good for his teeth. He used to bite and suckle before, but he's been acting up lately. I don't know what to do. We started giving antibiotics so early, and if we go to the doctor now, they will give him injections.
