Changing my daughter's diaper is what I imagine diapering a feral cat would be like. It is virtually impossible to get a diaper on that child. She rolls back and forth. Turns over. Sometimes when I think all is going well she'll just lurch at me, grab my arms and try to rip my sweater off and/or bite me.
This is also what it's like when I try to get the snot out of her nose.
I've never known a child who enjoys sitting in poo and not breathing full breaths of fresh air so much.
