My daughter is 3. On Saturday she went swimming came home and Sunday morning had no voice and runny nose. Sunday night she started to vomit. We took her to emergency Monday and they did a swab for strep and came back negative and said it was viral. Her voice returned Thursday and her appetite. My daughter is still throwing up since Monday and it s only at night time. During the day she eats normally but smaller portions an appears to be normal. Come supper she dies down energy but again seems normal enough. And once 8pm hits she vomits at bed an through night. It s foul smelling and all her food from the day is in there. No fever. No rashes.
