How to become a pediatric nurse?

Hi everyone!

I'm currently only a senior in high school but I've always dreamt of becoming a nurse. My grandma had a few extensive hospital stays and whenever I was with her, I watched the nurses and realized I wanted to be a person who helps others. However, I would love to work in pediatrics. I love kids!

I'm looking for advice on how exactly to become a pediatric nurse. I plan on attending a local public 4 year university and majoring in nursing. Besides that, I really don't know what the next steps are.

Please and thank you!
