I have had two babies in two years... I had an episiotomy with ds1 and gave birth lying flat on my back feeling sick from the diamorphine. Stitches were sore but soon healed.
Ds2 I had in the pool, a much quicker and easier Labour and my body just took over. I had him sitting up in the pool, and whilst i did tear I healed without any pain
I have had no problem with incontinence and aside from a bit of scar tissue all is fine "down there".
I think the increase in birth injuries may also be linked to an increase in inductions/sweeps instead of allowing bodies to go into Labour naturally.
Ds1 I had a sweep the day after my due date so whilst Labour started shortly afterwards it was very long and I was exhausted by the time it came to pushing, hence the episiotomy.
Ds2 I went into labour naturally he night before my due date and he was in my arms within 2 hours of getting in the birthing pool.
I think also people discuss things more now and recognise that they shouldnt have to suffer as a by-product of giving birth.
The risks should be discussed. I've had friends who have had inductions because "baby was measuring big" at 37 weeks and then had tiny 6 pound babies by emcs after days of failed induction because the baby was simply not ready to be born.
Obviously I'm not saying inductions are unnecessary but I'm sure they contribute. All my friends who have been induced tell me how horrific it was!
