at what age aprox do they stop this jumping bit, he thinks hes an iguana, im afraid hes gonna hurt himself one of these times jumping from my arm to the floor with a big splat sound then he gets up and looks up at me as if to say *see that didnt hurt at all* hes not even 6 months old yet but getting big and is less spastic as he was even a month ago. but he gets that urge to jump. usually i can catch him in mid air but not always. is there anything i can do to discourage this behavior ?
