Does anyone have any diaper changing tips or hacks to share?

When I was babysitting a friend's child for the night, I noticed that she had a small water spritzer at her changing table. I asked her what it was for and she said it revolutionised the task of changing diapers. Apparently, some of the hardest diaper changes are when baby poop is stuck to his or her bottom. Instead of using loads of wipes to scrub (and risk irritating baby's skin more), she fills the small spritzer with water with a few drops of baby oil and uses it to moisten poop that stuck on baby's bum for easier cleaning. I thought it was genius!
