I'm expecting baby #3 at the end of May. My previous two births were relatively straightforward with labours lasting 12 1/2 and 9 hours respectively. I've always assumed that births became more straightforward and also shorter each time but recently I seem to be coming across stories about how third births tend to be unpredictable and often problematic. I'm now starting to feel a bit anxious!
Have I just encountered old wives' tales or stories that owe more to coincidence? Or are third births genuinely unpredictable?
