3rd pregnancy!

So, i'm totally new to this but here it goes. we just found out were having another baby, and we are totally excited. I'm a little nervous about the labor and delivery though...I am seriously thinking about doing this one all natural...meaning no epidural. I have been looking online for tips and tools on how to make this go smoothly, but still a little concerned that i won't be able to handle it. I'm also interested in water births, but i don't know anyone who has done this. I guess if anyone has any advice for me it would be greatly appreciated. thank you.
