Well, mostly I regret the general arrangements for my first labour, but the epidural was part of it. Slow progress led to ARM, which stopped my contractions and led to syntocinon, epidural and forceps. No help with DD1 being back to back other than gas and air and then the cascade of intervention.
Next time I did it very differently. Wonderful home birth, with darkness, shouting my head off loud vocalising, positioning to try to move a (probably) wedged baby and an amazing birth in the pool.
When If there is a no. 3, I will be resisting the whole 'bright lights, coming and going, medical environment like the plague, and epidural is part of that. Me, hospitals and labour do not mix well it seems.
I also hated the catheter, having to have the drip in for an hour after birth, the fact that it wore off slowly down one leg (leaving me stranded in a busy post natal ward with no mobility) and that, despite being administered correctly, it didn't actually take away all the pain.
