D.P.
My son is the same way and has been since he was about 10 mos old. I made the mistake of blowing bubbles at him while on the table a couple of months back, and now he associates diaper changing with bubbles. He cries for "bubbles" over and over, but once I blow some bubbles, it helps keep his mind off the changing as he is trying to touch them has they fall. Also, he likes to be sung to while getting changed. Sometimes nothing works, and I have to take him by the arms or legs (whichever is flailing) and sternly say "No!". It makes him cry harder initially, but usually he quickly settles down after that. Anyway, I would like to tell you it gets better, but for me, it hasn't. Good luck!
