Hello, My 6 year old daughter decided it would be a good idea to use markers as nail polish. I told her to wait, that she can -only if- the markers wash off easily. By the time I returned from trying to get the marker off my ‘test nail’, she had already colored most of her nails, she hadn’t waited the few minutes it took. Now she has what’s best described as a stomach flu, with fever, vomiting, and lack of appetite. Could the markers have caused it? How long do you estimate the symptoms lasting? What remedies do you recommend and should I take her to the hospital? (She claimed to be feeling better after initially vomiting, but has another fever 12 hours later.) How serious is this? Thank you for your advice!
