Caught on video - surprising funny yawning baby

This is when my son Sammy's about 3 weeks old. Amazingly, we found him YAWNING WITH HIS HAND COVERING his mouth, almost like he's showing courtesy! Also, his eyes are tracking EVERYTHING around him. In fact, he started doing that ever since his 1st day after birth. I'm told by our Pediatrician that for a newborn, he acts and responds in a very mature manner. I'm definitely a VERY FRIGGIN' PROUD DAD....
