My son is only 19 days old. Since his birth every feeding (8-10 times a day) is a nightmare at least the beginning of it. He is fighting with my breast. He somtimes screams, cries most of the time. This can go on from 30 seconds to 10 minutes. After his fight ends he finishes with my breast without any problem and then falls asleep. I nursed him just few minutes ago and it took 25 minutes for him to end his fight. I'm using nipple cover to feed him as he has never got directly my nipple.
