question: My daughter had a headache yesterday but no temp. She seemed fine all day and ate like normal. This morning around 9:30 am, she vomited once and had a 100.3 temp. Gave here children s Tylenol and around 11:30 she started sipping flat 7-up. fever is going down and she is keeping the liquids down so far but her stomach is growling and she is asking for crackers. When can I give here something to eat?
