Thank you for your response. That is what I am thinking as well, but the thing is that she never did this before. She will be 11 on June 2nd, so do you think it has occurred due to her being a bit older?
She is eating and drinking just fine. Playful. Happy and way too spoiled.

I am worried that there is something else, like a brain tumor. When should I be worried if it is something that serious?
