Would it be better to consult, or should I continue taking Tylenol/Advil every 4 hours to relieve the fever?

It is always best to consult with a healthcare professional if you have concerns about your child's health. In the meantime, you can continue to give Tylenol or Advil as needed to help reduce the fever. It is recommended to seek medical advice if the fever persists for more than 72 hours or if your child's condition worsens. Additionally, using a saline nasal spray can help with nasal congestion and encouraging your child to drink plenty of fluids can also help.
