How to prepare?

I'm 18 almost 19 and pregnant, I'm more excited than anything, and feel I'm ready to be a mom. However I've been trying to think about what I should be doing and how I should prepare. I will have to share a room with the baby so it will be limited space. I already know the main items I need such as a car seat, crib, clothes, wipes, diapers, diaper rash cream, etc. Any tips? Thank you :)
