My son was having cough and cold on Friday, so we gave him soventus jr. Syrup on Saturday night, Sunday early morning he vomitted yellow colour at around 3 am then had breast milk and slept got up at 9 and vomitted again all white. Same afternoon did watery potty, and fever, we consulted doc, she suggested calpol for fever and Enterogermina, since yesterday there is no fever, did watery potty once in the morning but not eating anything still only on breast milk n water, also when he attempted to eat anything solid he does dry cough and pukes everything out. Pls help
