The need of a infant

At mass yesterday a baby was crying; I was wondering what can I learn from this.  Trying to regain focus I visualized myself back in time at the cross screaming "crucify him" with the crowd.   First I seen myself from the shoulder of Christ; I heard myself so clearly and felt disgust.  Then I heard and seen myself from the senses of Christ, we the crowd was crying and screaming from being soiled and hungry.  Infants was the crowd, the infants was the children of God.
