I was down with minor bronchitis last week. On Monday, all 3 of my kids got the virus from me and started high fever. My eldest child 4.5yo been vomitting since Tuesday morning. I think it is mostly cause of the phlegm. Tdy is the 3rd day she is still vomitting on & off. I did see mostly she vomit is phlegm but an hr ago she started vomitting greenish yellow substance. I'm not sure if it is phlegm/mucus or bile. Should I be worried if it is bile? Attached is a photo of her vomit with the substance on wet wipes. *Brought them all to doctor on Tuesday noon and was told to monitor for 3 days and if fever still persists, to bring back and start on antibiotics. *
