Potty-schmotty

So.... Luke is over 2.... he loves to READ on the potty, but rarely does anything else happen on there.  We have a seat adapter thing (as shown) and a small potty, but so far we haven't been successful in the potty training.  He is interested in the idea of potty, so we encourage him to sit, but he just hasn't
"GOTTEN" it yet.  I know they say that it takes a bit longer for boys to become trained, but we are going to shoot for full-out potty training the week after Christmas! Wish us luck!!
