my 9.5 month baby is constipated from around a month and has black powder like residue in stool. In her stool test, mucus and 2-3 pus cells are reported. alkaline stool, no blood, no parasites, Report is attached. Is it normal, when i consulted with my pediatrician before stool test she said just increase fibre intake. but stool test now shows pus and mucus.
