This is a normal phenomenon called gatrocolic reflex. Intake of food, stimulates the gut movement and causes passage of stool. Its possible your child, during these 3 weeks, has been exposed to new and different food. If there is no diarrhoea
or foul smell or blood in stool
or weight loss
, there is probably no cause for worry.Your child should be introduced to all food by 1 yr of age.
Please ensure that you dont give uncooked food. Water must be filtered , boiled and cooled. Please dont give bottled/mineral water without boiling.
Hope you are reassured.
