I need advice. Last night LO (6 mo old) woke screaming. Went to check on her and she had vomited all over. Cleaned her up changed her clothes and sheets and she threw up again. No fever, seemed happy as a clam, was playing as we cleaned her up. She didn't have any more vomiting episodes, slept decent, seems normal this morning. She did have a new food yesterday. We gave her carrots for the first time around noon. Can babies throw up 12 hours after getting a new food? We have a 1st birthday party to go to today. Do we go, since she seems fine? Or stay home in case it's a bug, so that the other kiddies don't get it?
