I am not a practising Christian, but the Bible has anticipated your question. Here is the passage from the Gospel According to Matthew, Chapter 19, Verse 14:
King James Version (KJV)
14 But Jesus said , Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven.
Revised Standard Version (RSV)
14 but Jesus said, "Let the children come to me, and do not hinder them; for to such belongs the kingdom of heaven."
