As per your history, your baby's diarrhea could be due to change in diet or can be infectious.
If baby is having abdominal cramps and blood passing with motion; then consult pediatrician
to treat infection where you need to take anti-biotics or anti protozoal drug.
If baby is just having loose motion
without blood passage or cramps; give him or her fluids as much as baby likes and give probiotic
like sporolac sachet two times a day.
Give baby curd to eat which is natural probiotic. It helps to deal with loose motion.
In case baby develops dehydration
like dry skin or no urine out put or drowsiness
, consult immediately the doctor.
I hope I have answered your query. In case of any doubt, I shall be happy to help you.
