Isn't this interesting?

Stumbled across these verses in Matthew:

The leading priests and the teachers of religious law saw these wonderful miracles and heard even the children in the Temple shouting, “Praise God for the Son of David.”
But the leaders were indignant.
They asked Jesus, “Do you hear what these children are saying?”
“Yes,” Jesus replied. “Haven’t you ever read the Scriptures? For they say, ‘You have taught children and infants to give you praise.’”

The Scripture that Jesus is quoting is Psalm 8:2.

Just thought it was interesting. Still thinking of the implications of infants being able to give praise. Is it instinctual? Or is "infants" in this verse referring to a child older than a newborn? As always, infant baptism is in the back of my mind...does this help the case for infant baptism? (I'm for it).
