My little love bug took a bottle of breast milk about an hour ago. It was 2oz and he's still acting hungry, before that I breast fed him for a half hour and he didn't wait 2 hours in between. He is constantly hungry and will eat more than 4oz every hour if I would let him. Just wondering if maybe 2oz every 2 hours isn't enough and if I should start giving him 4oz? He will be a month old on Black Friday.
