Hi, my toddler has been having gastro issues for the past three days. On Fri night he threw up twice in the night. Lot of undigested food and curdled milk came through. Then, it sort of settled and although he did not vomit, he was not getting much better. He had a mild fever on Fri but has been fever free since. We gave him 3 doses of Ondem on Sat and two on Sun. His appetite has been very bad all of this time and he largely has been drinking only liquids. Today, he only had some curd rice in the afternoon and that too when I forced it. This evening, he again threw up a lot. I pressed his belly because he said his tummy is full but he says there s no pain. He also is active after throwing up and seems better. Am seeing my pediatrician tomorrow. Should I be concerned about appendicitis or anything serious? Thanks!
