When I nursed my first two boys, they would stay latched for hours if I let them. They would wake up if I unlatched them when they fell asleep. It's so different this time around. He unlatches himself when he starts to fall asleep and he sleeps through the night with no boob. And he's a chunky boy, almost 16 lbs at 2 months, so I know he's getting enough. It's just so strange to me lol.
