There are plenty of websites that can teach you breathing and relaxing techniques during labor. If you are worried, search for them.
You're body/dr will know what to do. Don't worry. With my first they told me how to push productivity and everything. It's gonna be fine. Congrats!
I have 2 sisters and neither one took classes. And I won't either. Only 1 sister read the book. I think you will do fine.
I did not went to any class or get any baby book, I just went with the flow lol.
More and more mothers are opting out of birthing classes. I didn't take any either, I just pushed when they said too. Having a baby isn't really all that hard. Don't worry mama.
Haha, you'll be fine. I took no classes. It will all come, don't worry. May help with pushing if you ask for a mirror. As soon as I got a mirror I was able to get my daughter right out. I wouldn't worry.
