The kid looks
It is the first attempt of purposeful action, the child, seeking to catch a subject, intentionally gives to it hands.
The kid looks after a subject with which slowly drive here and there before his face.
If to enclose a rattle in his hand, it will strong squeeze it in a palm.
Only for a second he detains on it a look, but then starts swinging randomly hands and often beats himself a rattle and right there starts complaining loudly of it at this stage the child is not capable to shake a rattle randomly.
