I also use baby wipes, they are great for cleaning and freshening up little butts. One thing you said caught my eye. Your baby cries when you hold him to clean or trim his butt. These little furbabies are adorable but they are also very smart. Doesn't take them long to learn that if they fuss or cry mommy will let them go! My little one tried this with nail trimming. When I would hold her paw and she would try to pull away, she would cry. At first I thought I was doing something wrong but I soon caught on to her trick. When you are holding them to wipe their butt, you are not hurting them. Good luck with your baby and don't let him call the rules.
