Thanks for your query.
Yes dose is correct.
Probiotics are needed to replinish good bacteria in case if loose motions.
I also suggest you to give her plenty of fluids like lemonade,buttermilk
Give curd,banana,rice porridge.
Watch for features of dehydration
like decreased urine output/increased thirst/decrease skin turgor.
In case symotoms persist get her evaluated by pediatrician
for further management.
Hope this helps.
