Dd woke up this morning at 6am complained of bad headache had a wee went back to bed and promptly threw up on her bed. She has since vomited several times and can't keep anything down. I've tried her with a teaspoon of water method and as soon as she has the spoonful she vomits. She has a temp of 38.7 and a headache. No diaorreah. Will anything help this pass??? Unsure whether to give calpol or if that will make her ill has well
