Eh, 7.8kg at 1y4m tu memang on the lighter side, I understand your concern! Since dia dah kerap makan tapi still kurang naik weight, the trick is bukan just frequency, kena focus on kalori density jugak. So instead of just nasi, try mix in more protein and healthy fats: eggs, fish, daging, avocado, peanut butter, benda ni kaya lemak and kalori, lebih effective untuk weight gain.
