Thanks for your query
Your baby is having diarrhea
which is mostly viral in nature,and takes few days to settle.
Most important is to maintain proper hydration
I advise you to continue with breast feeding,give oral rehydration solution sip by sip after each loose stool
.Give lactobaccilus sachet for 3 to 4 days,zinc is to be given for 14 days.
In case symptoms persist i suggest you to get her examined by pediatrician
Wishing your baby good health
