Caden (4 years old) has Rubinstein Taybi Syndrome (RTS). RTS is similar to Downs Syndrome, which most of you are familiar with. Some of the characteristic of RTS are broad thumbs, broad first toes, lots of hair (Caden looked like little Elvis when he was born!), mental retardation, short stature/small size and various physical complications (Caden has several holes in his heart and struggles with constipation).
