'Little Child' in the Bible

Whoever shall receive one of these little children in my name, receiveth me; and whosoever receiveth me, receiveth not me only, but Him that sent me.

And they brought to Him little children that He might touch them: and the disciples rebuked those that brought them.

Verily I tell you, Whosoever shall not receive the kingdom of God as a little child, shall by no means enter into it.
