How much Tylenol and Motrin to administer?

As a parent, knowing the correct dosage of medication to give your child is crucial. Here’s a guide to help you understand the dosages for Motrin (ibuprofen) and Tylenol (acetaminophen) based on the information provided.

My Story

I usually alternate Motrin and Tylenol every 3 hours. I start with Motrin because it lasts 6 hours, and then after 3 hours, I pump it up with Tylenol. This way, I start with a bigger dose from the get-go, especially if the baby has a fever. This method helps manage the fever effectively and provides continuous relief.
