Hi, it's fantastic that you are so positive, I really think that helps a lot!!! It is quite natural to feel a bit nervous towards the end of pregnancy, and I don't think it matters how many babies you have every experience is different.

Set your goals, have a plan and be flexiable, sometimes you think you really will want something only to find out that you don't want that at the time.eg:labouring in water in my case, loved my baths the whole pregnancy, got the birthing suite with the bath, they ran it, takes ages.... and I was in and out in around 5 mins, preferring just to kneel at the side of the bed. Verus my first labour where I paced the room and remained standing until the very end.

Good luck, I hope you get the kind of labour and birth you are looking for. Don't worry about what others say, every experience is different.
