For the first two years after Ben was born I did monthly photos, and after the age of two I decided to continue do them every year for as long as these boys are willing to tolerate it anyway!
Here is Ben, at three years old. My sweet boy! He has grown so much, it kind of kills me. But, he gets sweeter and sweeter the older he gets.
Every year on his birthday I also measure his height on the door frame inside his closet. I love little traditions like that!
