How long does DS feed for? I found when my DS was 3 weeks I had to leave him on the boob for sometimes 45-1hr for him to really drain the breast and feel full and sleep. Community nurses and midwifes are okay, but in my situation they just gave me too much conflicting advice and most of it wasn't helpful or was outdated/incorrect. You are much better to either ring the ABA or see a lactation consultant
