Hi, thanks for using healthcare magic
You may need to consider taking her to the doctor for assessment. This would include assessment of her fluid status to make sure that she is not dehydrated and also sending a sample of stool to the lab.
The most important aspect of management of diarrhoea
is preventing or treating dehydration
. Even if she cannot use large amounts of fluid at one time, she needs to continue to drink, electrolyte replacement fluids would be the best option.
The doctor would be able to determine exactly how much fluids she may need.
Avoid solid food for now.
I hope this helps
