Hi Vineeta. Thanks for your query. Your baby is having acute gastroenteritis which is mostly viral in nature and takes few days to settle. Most important is to maintain hydration . Give oral rehydration solution sip by sip after each loose stool,give coconut water,lemonade,curd,buttermilk,boiled potato,banana,rice porridge in small amounts. Continue with zinc and also give lactobaccilus for 2 to 3 days. In case of vomiting antiemetic like domperidone can be given as per dosage. Watch for features of dehydration like lethargy/decreased urine output/increased thirst. In case symptoms persist get her evaluated by pediatrician for proper management. Wishing your child good health. God bless..
