With DD it was 17.5hrs of labour before a ECS and my milk came in on day 5, and breastfeeding just really didnt take off even after 6 weeks of expressing and trying to feed, no formula is just wasnt to be.

DS on the other hand was a 62hr labour which also ended in a ECS milk came in on day 2-3 from memory and hes nearlly 1 and still going strong with the breastfeeding.

One thing i think really helped was during the day feeding every 3 hrs at a bare minimum more if they want it and just going with the flow over night.
