Thanks for your query
Your Baby is having diarrhea
which is mostly viral in nature and takes few days to settle.
I suggest you to give oral rehydration solution sip by sip ,give coconut water.lemonade.curd,banana,boiled potato,rice porridge.
Also give lactobacilus sachet for 3 to 4 gays,give zinc for 14 days.
Observe for features of dehydration
,decreased urine output,increased thirst.and in case you find any get her evaluated by pediatrician
for proper management.
Wishing your child good health.
