Diaper debate 🤔...

Katera
I'm Tera, I'm 19, and this is my first pregnancy. I found out I was pregnant about a week ago and since then my boyfriend and I have been like chickens without heads and every now and then I find myself having a panic attack because I feel like I really can't do this I've always babysat and nearly raised my goddaughter but it's completely different than having one of your own (but I'm sure we all know that) . 
Anyway, I'm always open to tips, and advice from other moms and one thing I've noticed is that diapers are a bigger deal than I thought, and that some diapers are better for babies due to certain reasons so my question to you guys is: Which brand of diapers do you prefer and why? Also what kind of rash cream do you use? (just in case) I'm just here to soak up as much knowledge as possible so any advice is good advice.
