Hi M.,
My 18 month old is like that also. He tries to get up and cries. I try and keep some new cheap dollar type toys in the drawer in the changing table. When he is being really difficult I give him a new toy to play with. It usually occupies him enough to change a stinky diaper. I always take it back and put it away so that it is something special to play with. Good luck.
