definately insist they wait until after your spinal/epi - they cannot force you. Ive had 3 c/s - my 2nd was an elective and they put the catheter in before the spinal and it was horrible - i said never again - i had my 3rd elective 2 weeks ago and told them there was no way i would let them put it in before my spinal and they were actually quite understanding and no one kicked up a fuss - just warned me i would have an audience when it was done - like i cared after having 3 bubs!

definately stick to your guns, i aksed a midwife at around 30 weeks about it as i was already losing sleep over it - i know most people dont have bad experiences with them being put in - but once you've had one bad experience i think it would make you more tense which would make it worse.

have to say even after the spinal i could feel it going in but no pain or uncomfyness - just the sensation.

Good luck with your boys birth - wishing you all the best
