It is a good tradition. Little Krishna comes to our house as our child and eats the sweets and fruits in our house. As a child, as a little boy, as an affectionate youth, as a great scholar. as a great friend ...How lucky we are to surrender at his lotus feet as a devotee! "Krishnam vande jagadgurum."

Yes. They invite Lord Krishna to visit their homes and accept the prasadam that is specially cooked. Only after the puja, the delicacies are eaten and distributed to children. Small children are treated as Lord Krishna and fed with sweets. It is one way of showing your care and concern towards children and feed them properly.
