Yagya for the fortunate development of children is for getting divine blessings for your child’s progress. If your child is not able to get good grades in spite of them having the best mentors and tutors, if they are malnourished or not healthy in spite of a nutrient-rich diet, if they are not displaying the signs of personal growth and development, and if other symptoms, then this is just the right Vedic Yajna for your child’s progress and overall progress.
