Children should make Krishna and his devotees as their best friend, not the Computer.
Krishna is the ultimate purpose of all sacrifice. He is also the enjoyed of all sacrifices; therefore He is known as Yajna-Purusa.
The moonlike face of Krishna is the reservoir of nectarean songs and the abode of His flute.
Sri Chaitanya Caritamrta,
Madhya Lila, 2.29,
By scrutinizingly reviewing all the revealed scriptures and judging them again and again, it is now concluded that Lord Narayana [Krishna] is the Supreme Absolute Truth and thus He alone should be worshiped.
The Supreme Personality of Godhead Sri Krishna is the only enjoyer. Everyone and everything else is the object of his enjoyment.
