My baby is 4 months old now. For the past 3 days she is passing soft stools around 3 to 4 times per day. Her stool is having too much of mucus and somewhat sticky type. Her stool occult blood is negative, reducing substance is absent, stool reaction is acidic and few fat globules are present. She is also having low appetite for past 3 days. She is on breastfeeding as well as on formula milk. Please suggest what to do now.
