does anyone's

Re
Baby latch on and not let go even when they are full. I feed my son for 30 minutes on each breast. A couple of nights ago I did 45 minutes thinking maybe he wasn't getting enough. After the second 45 minutes was up he still wouldn't let go so I had to pull him off which isn't easy because when he realizes I'm pulling him away he latched on extremely fast and it really hurts to get him off. I started to burp him and he threw up almost all of what he ate. So I'm just wondering if anybody else's baby does this too or if he's the only one
