Thank you for your query on Healthcare Magic.
Your child seems developed gastroenteritis
mostly due to a virus.
Continue frequent exclusive breast feeds to maintain hydration of the child.
You can give oral rehydration solution like Pedialyte
to maintain hydration of the infant.
Monitor hydration by her activity, urine output, and skin turgor.
and zinc can be added with doctor prescription.
Consult the doctor if the loose stools are continuing, for physical examination and treatment.
Hope I have answered your query.
