Nursing/pumping schedule

CJ

Hi ladies. Currently 2 weeks postpartum and struggling to find a nursing and pumping schedule. Baby girl usually gets 1-2 bottles a day, one being right before bed but throughout the day we nurse. Bottles were only introduced this early due to her NICU stay. She feeds every 2-3 hours and I’m struggling to figure out how often to pump. Also, how long do your nursing sessions typically last? TIA!
