Any idea why my 6wk old will root on my nipple aggressively but never latch?

🤰🏻

This has been happening the past week. She will be crying and i put her to the breast and she will root on my nipple violently lol and never latch and starts crying clearly frustrated. I usually just move her to the other breast where she will usually latch. This happens when my breast is full or soft so its not that my breast is too full…
