After 2nd S&S, I had a fairly long latent stage, (2cm dilated, 1 min ctx every 3 mins for about 24 hours) which wasn't really going anywhere very fast, and I was throwing up a lot. I was thoroughly miserable, thinking I wasn't coping with what was supposed to be the easy bit. I had two lots of pethidine, which let me sleep a bit and got me through to having my waters broken (at 40+12, so technically due to dates rather than failure to progress).
After my waters were broken, everything all started going somewhere, and DD was born four hours later. That turned out to be the easy bit!
But, looking back, she was really sleepy. She hadn't fed properly before we were discharged - they'd seen her latched on sleeping, but that's not quite the same thing. She lost a lot of weight, we were readmitted, and we never managed EBF (though she was weaned at 18 months - my choice).
If I were to labour again and be in the same situation, I would like to think I could get through the first bit with less miserableness, knowing that I can do the pushing bit OK. And if not, I would insist on more BF support, and a proper plan to get back to EBF if formula top-ups were required.
