baby coming tomorrow via section so nervous!

Lisa
Any of you lovely ladies had a planned section before? 
This will be my second section but my first was emergency and rushed in the sense I didn't have time to register anything. 
How does it all plan out? I've had my Pre op Friday but it was pointless as I wasn't given a run down or anything apart from the usual check etc..
My stomach is in knots and I'm so emotional for leaving my 3yo for possible unoriginal 3 nights depending on how it goes.. I'm in the U.K. And feeling a little scared to be honest 😔
