Should I make her a doc appointment? She jumped out of bed having just woken up, looked in her sisters room to see if she was up (right next to her room) and said she couldn't see at this point and was dizzy, then I heard a thump and called her but she didn't answer. I called again and she said 'I'm fine' and then came in and told me about it!
I think it could be a lack of iron maybe?
She is 13.
