Dd2 is 3 days old, my milk came in much earlier this time and I seem to have excess supply, baby has wees, poops, feeding as much as I can get her to but not draining the boob and only doing one side per feed. I remember dd1 sucking for hours and taking everything early on but she was 2 lb smaller at birth, and milk came in only on day 4/5. So what age did yours drain the boob/start feeding both sides?
