Baby cant stay awake

During feedings.

I breastfeed as well as bottle with pumped milk. The last few days he wont wake up no matter what I try after him falling asleep while feeding. I know he isnt getting what I need and it's really frustrating because an hour later he is hungry..and the same cycle repeats and repeats.

Not sure if any other moms are having the same issue and what you are doing to help with this.

I really want to breast feed, but I feel I should switch him to bottles so he gets what he needs?
