Good evening young man!!
So strange, I was talking to my mother about precisely this just yesterday!
Harry will be 4 in October, and over the past couple of months we've noticed subtle changes in him. It does depend very much on who he's with, he can be wound up or really chilled accordingly.
But he seems to have reached a point where he maybe feels so safe and secure and 'knowing', that nothing seems to bother him the way they used to - even the post-lady's safe....and the man that (for some reason

) he can't stand at No.5!!!!
Love and a hug to you all from Harry + I!!
