These are not ordinary children, they are Vaikuntha children and we can give them chance to advance further in Krishna consciousness. That is very great responsiblity, do not neglect it or be confused.
Teach them Krishna consciousness at early age.
The living force is always dynamic; therefore he cannot stop discharging duties. Real duty begins in Krishna Consciousness.
The Lord may assume the form of a baby or a shape other than that of a human being, but it doesn’t make the slightest difference; He is always the same Supreme.
Srimad Bhagavatam 3.2.23,
There is no question of darkness where there is light and Krishna Consciousness is the light that dispels the darkness of material sense enjoyment.
Teachings of Lord Chaitanya,
Krishna Consciousness means diving into unlimited Spiritual Bliss.
