Thanks for your query,
sometimes takes longer time to clear,continue with nystatin application.
For diarrhea it is mostly viral in nature.
Continue with breast feeding.
like lactobaccilus sachet for 3 to 4 days.
you should avoid gas forming food items in your diet.
watch for signs of dehydration
like lethargy/decreased urine output/refusal of feed.
In case symptoms persist get her evaluated by pediatrician
for proper management.
Wishing your baby good health.
