The pictures are creepy. But kissing your son, and even cuddling are not necissarily sexual. In this case context is everything. I think the biggest factor in making people feel sick is that most kids that age are well into puberty and would not be comfortable doing that, so we try to rationalize what we see by assuming the boy was groomed to accept it. But it looks like the kid is a late bloomer and just hasen't reached the point where he is disgusted by affection from his parents. He should not have taken photos like that, let alone posted them. But I would not call him a pedo over this.
