Neonatal nursing- I would like a little bit of information on it.

Sorry it is so long, thank you for taking time to read this, I would really like some answers. I am 14 years old, nearly 15. Freshman. I am looking to go into Neonatal Nursing. What are some things you recommend as far as programs of study (extra classes helping you advance in a particular field.), colleges, other things like that. By next January, I will have some experience caring for newborns because my mother is pregnant with twins, so lucky me. I've been going to her appointments, but now that I'm moving in with my dad I've not been able to be with my mom. They only live 30 minutes apart so it isn't that big of a deal, but her next appointment I'm planning on going to see I I can job shadow. Anyways, what are some things I should look into? It'd be great if I got serious answers rather than stupid, uncalled for comments. Thanks. Also, I live in Chattanooga, TN. Does anyone know of any volunteering programs at Erlanger if there are any? I want to go ahead and kind of explore the field before I go and sign up for classes.
