Breastfeeding is honestly a 24/7 job.  Newborn babies nurse multiple times an hour. My son would wake up every 20 minutes to nurse, and would scream every time he delatched, to the point where he slept attached to my boob, nursing all night long for the first 2 years of his life.  I'm talking, his boob was on my mouth from 9pm to 8am, sealed.  But hey, kid has the immune system of a fucking Greek god, so no regrets.
