Hungry babie

I am kind of afraid of electric pumps..u sure it doesnt hurt..does it pump too fast or is it like a baby’s suck?
No not yet my FIL had his open heart surgery yesterday so I’ll go later this week..i just figured that sore nipples r due to engorgement..and now when I feed her its the pressure on the areola that hurts while feeding..but its better than before alhamdolilah..cracked nipple is also healing i guess..
Should the nipple b sideways or at the center of baby’s mouth?
