My son is 12 and half years old. He passes a lot of flatus and many a times it smells. Although his diet patterns are almost normal and on time but water intake and intake of daily fruits and salads is less. I try to include lot of vegetables in his tiffin recipes but fruits he consumes after a lot of persuasion. His physical activity is good for his age. Please help me how to motivate him for more fruits and salads and reduce his flatus.
