Does breastfeeding actually get easier for your partner after the initial hell?

My wife is 2 weeks postpartum and her nipples are absolutely wrecked. She's in pain every time our daughter latches and it's heartbreaking to watch. Everyone keeps saying 'it'll get better!' but nobody explains the actual timeline. Is it weeks? Months? She's determined to keep going but I'm worried about how much longer she can handle the pain. Anyone have real experience with this?
