Evening time nursing issue

Kylie

So for the past week when my 7 week old eats anywhere between 6-9 he FREAKS out when he’s trying to nurse. Like complete meltdown. Bangs his head against my breast, kicks and cries. He generally calms down when I just stop trying to nurse him but it’s been happening basically everyday for a week or more and I don’t know what to do. Why is this happening? Please help!!!
