i wouldn't under estimate yourself!!! its logical to be afraid of the unknown, however the female body is incredible! If you keep reading you'l find stories of women who explain their experience as calm, relaxing (orgasmic if u believe it ) you may not know what to do, but your body is designed to do its thing and get bubs out
there's a few home birth and hospital birth vids on youtube, worth watching! There's a few youtube vids of Ina May Goskin (sp?) she suggested kissing in labour to relax and open up down there, ive known that bit of knowledge for my last 2 bubs and do u think i wanted a smooch in labor??!! hell No! LOL! Some things you wont know until the time comes e.g will i snack thru labor?
I am proud to say i have donated my healthy cord blood depleted placenta to a hospital birthing class.. (yay for grossing out soon-to-be-parents!!) The hospital birthing class i went to with #1 just made me confused, they can't all be bad tho!
All the best!!!!!!
