My 3 week old son has a small but very painful rash on his bottom. It appeared overnight for the first time, so I started putting a zinc oxide cream on it and trying to change his diaper as often as possible. The poor little guy is in so much pain that he screams when I wipe him and apply the cream. I tried a short baking soda and lukewarm water soak earlier, which didn't seem to do anything. If anything, the rash looks a bit worse now than earlier, like the skin is raw. Poor little peanut screams his head off every time I change him

Any suggestions? My mom said Vaseline, but I'm not a big fan of petroleum jelly. I'll do it if it works though. I'm also trying to make sure the area is dry before I put a new diaper on, but even blotting with a tissue hurts him.
