My 5 year old son is recently facing this problem of morning sickness/nausea from last 10 days. He vomits in the morning and he is fine the rest of the day. Earlier he used to have milk and then go to school. Now he vomits milk in his bus or school or at home only. Because of this he diet eat his tiffen also. Teacher said he makes faces as if he will vomit while eating tiffen. So literally he is empty stomach for 16 hours since last night dinner. Paed prescribed lanzol n rantac for 3 days but no respite. He feels vomitish even empty stomach in the morning. Its affecting his studies now. please help.
