This is a funny and amusing video of a precocious little boy just hearing his mother's news that he's going to have another brother or sister. It also demonstrates a very common nonverbal signal seen when significant news is heard, seen or realized.
During the 0:03 - 0:04 segment, this little boy covers up both or his eyes with the palms of his hands.
This is one body language manifestation indicative of emotional processing. The logical mind knows what is being seen, heard or thought - but the emotional mind needs some time to catch up to what the rational mind more rapidly assimilates.
