Painful letdown??

Katie
We've been breastfeeding for a week as of today. Starting yesterday I've been having pain when he first latches on. The pain has only gotten worse in the last 24 hours. It's to the point I kinda dread feeding him. But once he's been on for a minute or.so the pain is gone. So based on what I've read I think this is pain caused from let down. .... is there anything I can do to reduce it??
