Hello! Welcome to HealthcareMagic! Thanks for asking. A two year old child, if fed only on milk, is likely to pass pale motion. In addition to milk, the child should start eating food including cereals/pulses in semi-solid or liquid form. Boiled vegetables, soups, mashed fruits for having a well formed stool. If not, he needs to be investigated for liver problem. Give him sufficient food /water for having natural motion. Bowel training by attempting bowel movement at a fixed time would help. Add syrup of fig half to one spoon daily/syrup of Aloe Vera would help. Consult his pediatrician for expert opinion Hope this clarifies your concerns. Thank you for the query. Take care Regards, Dr. Vasudha Jayant Athavale, General & Family Physician
