Oh do I feel your pain! My daughter is so wiggly. I swear, if the government could tap into her energy supply we could power the entire state and she STILL would have enough energy to play and grow! ha ha ha
She hates diaper changes. She basically hates anything that interrupts her regularly scheduled program of PLAY! :-)
That being said, distraction is my BEST friend!
When she is extra wiggly and very uncooperative for diaper changes or getting dressed or something, I give her something 'forbidden' to play with. Something that is not harmful, but that I wouldn't normally let her play with. The forehead scanner thermometer, the nose sucker thingy (seriously, aspirator just isn't as fun to say), The medicine dropper (ours is really large), stuff like that. Most of these items are kept close to the changing table, so they are in within easy reach.
I have found her curiosity is so high that if I give her something 'fun' to play with then she becomes so intrigued with her new play thing that I can quickly get the diaper or clothes on with no issues.
