I have had physiological third stage for all 4 of my births... Pretty much a 'non event' every time. After pains have been pretty awful the last two but not until AFTER third stage. #1, 2 & 4 were really quite quick like within 15-20mins im pretty sure. #3 was longer but likely because I'd had a precipitous birth and she wouldn't stop screaming her head off to bf for the first half hour, once I managed to get her to settle and attach for a few mins I went to the loo and gave a little push and it was all over, about 45mins all up. As for bf etc I'd say same as any birth... Get baby attached asap, preferably within half an hour of birth and skin to skin. Keep in mind that you can feed laying down (eg getting stitches) just that closeness and stimulation for you and baby is great for hormones and bonding. The strong desire you have to try again is a real positive start
