--Yes, the Bible does instruct us to have child-like faith and to "Train up a child in the way he should go and when he is old he will not depart from it."
--(Proverbs 22:6)

When the Disciples told Jesus to tell the little children to go away, Jesus said, "Allow the little children to come unto Me, for such is the Kingdom of God."
Jesus loves little children.

"And all thy children shall be taught of the Lord; and great shall be the peace of thy children." --(Isaiah 54 verse 13)~
