My four year old daughter got sent home today from school as she had stomach ache and her hands were really cold. She has not eating anything all day just had a little to drink, she's complaining of a headache along with her stomach ache and she feels very warm now, her hands are no longer cold but her feet are. Also her eyes look glazed. She's been sleeping most of the day, waking up when she feels like she's going to be sick but hasn't actually be sick. I'm unsure what to do.
