Hi
Thanks for your query,
Oral thrush sometimes takes longer time to clear,continue with nystatin application.
For diarrhea it is mostly viral in nature.
Continue with breast feeding.
Give
probiotic 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.
God bless.
