Babies r us offers all sorts of free birthing classes, for almost everything you will be to know. Idk where you are located, but you can look it up online and see what the store near you has.
I'm a first time mum too. I will be going to the classes. Even though the books and internet are detailed I feel you can't go past the human touch. You will also meet other mums and be able to share your experience face to face. If you don't want to go alone take your partner/family member/or friend who will be with you during Labour. Hope this helps, good wishes xx
