I have 5DC, currently pregnant with my 6th, mine have got earlier each time.
1st- induced- pessary and waters being broken. 4 hours long, minutes pushing, a bad tear and 6lb 11oz just short of 42 weeks born at 15.31
2nd- spontaneous, early labour signs from about 35 weeks, contractions started on due date kept stopping at night born 40+5 at 13.52 via assisted delivery after 2 hour pushing. 9lb and back to back waters were broken at 7cm for me.
3rd- spontaneous, early labour signs from 33 weeks, 6 days of stop start, born at 38 weeks, 6lb 13oz, 7 mins of pushing born at 13.56. Waters were broken at 6cm due to slow progression.
4th labour signs from 28 weeks, spontaneous delivery at 34 weeks, waters were left due to preterm and ruptured whilst pushing. Back to back. Born at 13.01 after about 10 minutes of pushing. 5lb15oz
5th labour signs from 24 weeks, labour stopped by medication at 30+4, born at 31 weeks by crash EMCS at 8cm at 23.52am 3lb 14oz. Waters were broken for me at 5cm to try and get her out faster.
Slow labour seems to be consistent with dc2 onwards but they was all so different apart from waters are a pain to go on their own. Now 26+3 and no idea what to expect this time..
