La mazae classes and caring for your newborn classes a lot of the time are available at the hospital you are giving birth at (at least around where I am at) check at community centers and look on the internet.
I think that when your baby comes you will surprise yourself on how much will come naturally to you. I mean you will probably put the diaper on the wrong way a few times but you will get the hang of it. Maternal instinct is something most women are blessed with. Youll do fine. Good luck!
Ps read up on the issue. That can be a big help. And if your close to your mom I think that they are the best teachers. (well usually)
