I had premature rupture of membranes at 36 weeks with my first child, and labour stalled. I was given 72 hours but was required to take oral anti-biotics to help prevent infection. After 72 hours, I was still only having random contractions so went back to hospital and was put on syntocinin IV drip. I was disappointed at first but it all went well. I had a 7 hour labour, no pain relief drugs and a vaginal birth.

I wish you and your wife all the best. How exciting!
