Thanks for your query.
Your baby is having diarrhea
and most of the times it is viral in nature and subsides in few days.
Most important is to maintain hydration.
This is good that she is active,accepting feeds and urine output is good.
Give oral rehydration solution sip by sip after each loose stool
,give coconut water,lemonade,curd,boiled potato,banana,rice porridge.
Continue with probiotic
and give zinc for 14 days.
Antibiotic is needed if she had any bacterial infection.
If symptoms persist get her re evaluated by pediatrician
Wishing your baby good health.
