the c section's are just a small incision and you generally can be awake for it - it's just the healing time for the Mom is longer and she needs help lifting and carrying the baby.
Watery/Stars: it all depends on when you were born...when my sister was born they sliced my Mom down the middle and she has a big scar but now they do a bikini incision so it is hidden. I've had a few people I know do C sections and you can't even tell. 2 of them had repeat c sections and no noticeable problem. And one had a csection for the first and then had VBirth for the next 2.
well, never actually having had it done I can't say... I only go by what others have said...and everyone is different for recovery, pain thresh hold etc. Depends too whether their stomach muscles were fit to begin with, lots of factors.
