Hi Shandon!
Oh gosh! I remember those days! Just last week it took me, my mom, AND my sister to change a very poopy diaper because my 11 month old nephew is WAY too wiggly during diaper changes!
I tried many things with my boys, but the one that worked the most was when I sang the ABC song or counted to 30! I would say, "I wonder if Mommy can change your diaper by the time I sing all the ABC's". I picked a nice slow pace, so my boys could learn their ABC's as I sang them. Before I knew it, they would try to sing along with me, and diaper changes got easier and eaiser..... When we had a REALLY poopy diaper, I would have to say, "oh my goondess! I thnk I have to sing the ABC song 3 times for this diaper!!!!"
Anyway, I hope my silly games works for you!
Good luck!
