Hello, Thank you for asking at HCM. I went through your son s history and would suggest for him as follows: 1. Infants, especially younger than 6 months, can have variable stool habits. It may be quite normal to pass loose stools. So if he does not have vomiting, fever, poor feeding, excessive crying, irritability, if he is playful and if he is passing urine normally, please do not worry about loose stools. I would think of it as normal and there no need of treatment. 2. Passing stools after feeding is also normal at this age, it is called gastrocolic reflex , it improves with age. It does not need treatment. 3. It is possible that gas in stomach/intestines may be causing him fussy, which can be taken care of by burping while feeding. 4. It is great that he is on exclusive breast feeding. I would encourage exclusive breast feeding up to 6 months of age. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish your son the best of the health ahead. Thank you & Regards.
