<s>[INST] My one year old son woke up this morning and has vomited repetitively since then. I tried giving him pedialite, but it did not stay down. I have given him small amounts of water, but that comes up too. He has been sleeping on and off all day. He is not cranky and isn t being colicky. Just lethargic, sleepy, and vomiting. Not fever present. What should I do? [/INST] Welcome to the ChatDoctorRepeated vomiting without any fever might be due to VIRAL gastroenteritis or gastritis. In my opinion you may try an antiemetic such as Sup. Meet along with Junior Landon dispensable tablet. This should be followed by oral fluids such as lemonade or butter milk or a plain ORS. If he tolerates, continue same. But in case he continues to vomit or remain lethargic, consult a pediatrician so that a proper clinical examination can be completed to search for cause of persistent vomiting and lethargy. </s>
