My son is 7 months old. He went into the Doctor on Tuesday, and we found out he has his first ear infection. They put him on Amoxicillin. He took his first two-doses Tuesday, and has been taking it twice a day. This morning, he has this rash on his belly, and only on his belly. Called the dr, they didn’t seem concerned, and said it can happen. He also has had diarrhea too, which they said would be a normal side affect. Being a first time mom, I’m just freaked out. What should I do? Is this normal? When should I worry? Etc??
