Hi. Avoid cow's milk or packet milk till 1 year of age. Continue breast feeding and give first foods like Ragi porridge, cerelac etc. If breastfeeding not adequate then give formula milk by spoon and cup and NOT bottle feeding... Nanexcellapro is a better milk than  lactogen as it is close to breast milk in composition..its costlier than lactogen. Pls give him sips of water in between feeds. This will also soften the poop...
