my baby is 14 months old. she takes 3 meals 2 snacks including suji, rice,daliya,roti, vegetables, fruits(banana, apple), milk( 1 time formula, 1 or 2 times cow milk). water intake 750ml/day. now a days her stool gets so hard that blood comes out. what is the reason for that? does cow milk harden the stool?? if yes then what is the alternative to cow milk(full fat milk)??
