Brothers....Look Alikes

It's no secret that my older boys look very much alike and that they all bear a strong resemblence to their daddy. From the minute they placed Nate in my arms at birth, I always felt that he looked like a replica of his big brother Nolan. All three boys have such a strong resemblance that I have had to be diligent in labeling photos so as not to get them confused. Although Garrett looks similar to the other two, he has some distinguishing features(like his enormous blue eyes). Each of them has a very distinct personality as well. As Nate is growing and maturing, his features are beginning to take on more of Nolan's characterisitics and to look even more like Nolan. Sometimes it is almost as if I am looking at clones(except for the height and age difference)...What do you think?
