yes EASY cannot go on demand. i nvr fed on dd from day 1 so i dunno how to advise to switch from dd to schedule feeding.
to move from 2 to 3 hr routine, focus on getting a good latch, dun let bb fall asleep, make sure it's a full feed. i know it's tough, i oso hv trouble.
try to stretch intervals incrementally n watch for hunger cues as u go along,
