My little one who’s 22 months old developed a fever in less than 4 hours. She was fine all day long but when around 9PM she was at 102.4 degrees. I gave her Tylenol but her fever kept rising. This is the first time that had ever happened. I never had a medicine not work. I knew I had Motrin somewhere. My pediatrician told me when fevers get real high, give Tylenol and Motrin at the same time. In this case at 11 PM, her fever crept up to 104.4. After giving her Motrin, within 30 minutes, her fever was down to 103.1. I’m relieved but I’m still going to call the doctor in the morning. I guess I’m not going to sleep at all tonight.
