The baby, according to what you have said, seems to be listless as she probably is under dehydration
. Try to give her plenty of liquids including electrolytes. The dehydration could be serious if the child does not pass any urine at all or passes only high colored scanty urine. This could be a teething
problem; infections set in as children bite everything and anything that comes in the way to control the itching they face while teething. Since the diarrhea
has been there for the past four days, it is better if you can take her to her pediatrician
for an antibiotic and may be electrolyte replacement. Take care.
