And the Answer Is. . .

First picture-Ammon
Second picture-Caydin
Third picture-Isaac
I would say that Isaac and Ammon look the most alike.  Caydin had a lot more hair at this age then either of the other two, and it was much more red.  When we gave him his first haircut, the hair underneath was blond, which is when he became my first blond kid!  But, even with the red hair, there is no doubt these three boys are brothers!!!
