Hello madam, Thank you for asking at HCM. I went through your history and understand your concern. I would like to make suggestions for you as follows: 1. In general, I would suggest exclusive breast feeding (nothing but breast feeding, even not water) to baby up to 6 months of age. This is because breast milk helps to build immunity of the baby and protects him from many infections. So I would suggest you to try to shift him on only breast milk as early as possible. You can gradually increase breast feeding and gradually decrease formula. 2. It is good sign that with breast feeding, he is urinating more. But if he feels hungry quickly, it means whole breast is not getting empty. I would like to mention here that the first part of breast feeding (foremilk) contains more water and the last part of breast feeding (hindmilk) contains more solids. So at present, he is getting more of watery part from breast feeding. So please make sure that when you breast feed him, whole of the breast is getting emptied first, then only offer the other breast. This will satisfy his appetite. 3. To ensure better nutrition for him, I would suggest you to take plenty of fluids during day and a nutritious diet so that he will get nutrients from the breast milk. Please avoid stress and be relaxed while breast feeding as it is very important for milk production and milk let down. 4. I would suggest you not to worry about occasional gas and change in bowel habits as it is common during first 4-6 months of life. 5. If still he is not satisfied and not gaining weight over time, then only I would suggest you formula or any feeds other than breast milk as per doctor s guidance. Hope above suggestions will be helpful to you and solves your query. Should you have any further query, please feel free to ask at HCM. Wish your baby the best of the health. Thank you & Regards.
