My 4-year-old daughter has had a fever for 24 hours, but it hasn't gone down (39.9) even after taking a dose of Advil and Tylenol. Should I consult a doctor?

Yes, if your daughter is still experiencing a fever despite taking Advil and Tylenol, it would be advisable to consult with a doctor. It is important to follow the recommended dosage guidelines for both medications and monitor her fever. If her fever persists or worsens, seeking medical advice is recommended.
