Weird Camera Angle when Trying to Attach Camera to Head Bone

Hello,

I am trying to add a first person camera to the "Ethan" character's model. So, I made the first person camera a parent to Ethan head in his skeleton. After doing that, whenever I would play the scene, the camera was either slanted up way too high or rotated upside down. After that happened, I tried to fix the transform of the camera, and the camera preview looked good. However, when I would play the scene it continues to appear extremely slanted or rotated upside down no matter what I do. I have tried to research this, and I have not found any answers to this. What am I doing wrong here? How can I get the camera to properly aligned when I play the scene?
