The Magic of 6 weeks

I had heard that something magically happens to babies around the time they turn 6 weeks old and it was a few days after Derek turned 6 weeks that he started sleeping longer at night (some nights are still a struggle) and is much more active and talkative during the day.  It's actually kind of fun to watch him get so excited about his toys and learning the world around him.  This was taken after changing his diaper today:
