Does anyone know what this is? All I know is its not a scratch.

Looks like a blood mark. As if she laid on her arm in such a way that it pinched the blood up to the skin.

Did she have a long sleeve shirt on that might have been too tight?

She could have run her arm along the edge of something. With enough pressure you can create a bruise like that without breaking any skin to cause a scratch.

@sawyersmom sort of but it popped up after I took it off so could it still be it?

@jessicavillanueva92 I thought she scratched herself but its more like a bruise. There's one on the other side of her arm too.

@lovelily she was laying on her daddy's chest I'm not sure if she was on her arm or not. So that may be it

Did he have a necklace on that she reacted yo the metal

I think her shirt was too tight honestly. It looks like where the seam laid on her arm

@rola no just a shirt

@sawyersmom yeah that's what I'm starting to believe
