HI, I understand your question & concern -Vomiting is normal in pregnancy. It s due to increased pregnancy hormones to which mothers body is not used to.Usually it disappears after mother s body gets used to it. ( by 3 months pregnancy)Severity of vomiting depends on mothers sensitivity to hormones. Usually non irritant/non spicy / sour /cold food items are well tolerated. * She has to take rest/ can continue with cold milk diet ( 1 to half cup with sugar every 2 hours. She can have alternative food ( except above mentioned ones-) in between in small servings. - Anti emetic drugs( Doxinate) / antacids ( Ranitidine)can be added as per your doctor s advise. * It s not a big problem ,provided she completes her nutritional requirements. If not take her to your doctor for medication/ Iv drip as per need. It will resolve by itself in 3-4th month at the most. Thanks.
