Ok so I am trying to ebf but lo doesn't like to wake up at night to eat (yes this is a blessing and a curse). i try for an hour to wake and feed but have the time lo is just sleeping at my breast. its so frustrating! i want to feed at least every 3 hrs because she needs to keep gaining weight but she is so sleepy. if i pump she glady takes the bottle---do u think this is something i can just start doing every night to avoid major loss of sleep and sanity? i am fighting with dh almost every night and i am starting to resent baby in the middle of the night. lo does ok during the day with nursing for the most part. help---and thank u
