Lincoln and Byron Ryman are identical twins, although it might be a couple years before anyone has difficulty telling them apart. The twins were born 11 weeks premature, and doctors thought that Lincoln (the smaller of the two, at just over 1lb) wouldn't survive after they noticed he had stopped growing early in the pregnancy.
Amazingly, both have now started gaining weight and are expected to remain healthy. Link [Daily Mail] via Unique Daily

I just hope that their mom doesn't run off to an Artist's commune...Sorry could help myself.
Although, looking at the picture, I can't help but think of Caramon and Raistlin.
It's hard to tell them apart now, 18 months later, as they tear around like mad-toddlers!
