Latching issue? FTM here.

Courtney • Baby #1 due August 1, 2019! 💗💗

I had my little girl on July 26th and she has been nursing great since she was born but sometimes she will try to latch and pull off and try to latch and pull off and she will get frustrated and move her head all kinds of ways until she is screaming.. I’m not sure if she is having an issue latching or what? I’m so confused and it is so frustrating to see her so frustrated. She will eventually latch and start feeding but it can take a little bit.. anyone have any input? She has been nursing great which is why I’m not sure what the issue could be now. Sorry if this doesn’t make sense but it’s hard to explain.
