Hi my babygirl has 7 month and she's been having a fever since Saturday night. I took her to an emergency clinic yesterday and the doctor didn't find anything wrong with her but still gave her an antibiotic shot. We left home and she seemed fine but the fever came back a couple hours later and had fever all night. So we decided to take her to the hospital at 4 AM because I was l think it's too much already. So we took her to the hospital and the doctor said she doesn't have anything no infection. He didn't see anything wrong with her other than the fever. So we got sent home and she still has a fever. I'm really scared and I don't know what to do. I'm a first time mom I'm freaking out right now please help me. By the way she doesn't have teeth yet and I don't see any breaking in. Also she has diarrhea just started today. 😢
