I have certain questions and suggestions for you. Questions:1. Did your kid pass motion or meconium on day one of life?2. Since how long is the kid constipated?3. Does the kid have any bleeding along with hard stools?4. How much milk does the kid consume per day?5. Does the kid eat fruits and vegetables (fiber diet) appropriately? Suggestions:1. Natural methods are the best to relieve constipation.2. Constipation is a risk factor for UTI3. Maximum milk consumption per day should not exceed 300-400ml4. Minimum 3-4 cups of fruits and vegetables to be consumed per day5. Toilet training - that is - sitting in Indian type of lavatory daily at the same time will help a lot. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome.
