It is the duty of all parents to make their child Krishna conscious so that the fortunate child may not have to take birth in the material world again.
If you train a child in taking shelter of Krishna then that will become nature of child.
Children should make Krishna and his devotees as their best friend, not the Computer.
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.
Total absorption in the thought of Sri Krishna.
