Re: Screaming and crying at the breast
How awesome that the baby nursed! Well done, mama!
Okay, breastfeeding isn't something that babies master immediately. It's a skill that they have to work on. They have to learn how to control the flow of milk so that they can transition from nursing for nutrition (fast flow) to nursing for comfort (slow flow). Your baby is used to getting his comfort needs met with a pacifier, so it may take him a while to learn how to make that switch in his sucking.
Once a baby is no longer hungry, what happens next depends on the baby. Some babies will spend a long period comfort sucking at the breast. Others will rapidly turn away and "ask" for a paci (if they're used to pacis, that is) or will find their own fingers/thumb and suck on that.
Transitioning from measured feeds and bottles to nursing is definitely difficult. You have to learn to trust your body and your baby! Watch your LO's diaper output carefully during the transitional period. If he continues to make sufficient wet/poopy diapers (and remember that after 6 weeks poops can slow to as little as 1 per week), then he's getting enough to eat.
