I was on my layover at an Arizona airport when I decided to take advantage of the time to do a diaper change for my son. As I entered the restroom, the changing table was being used by a young mother who was changing her infant daughter's diaper. I could tell the baby girl had a bad diaper rash, but I didn't really want to pry. I wasn't sure if or how the mother was handling it. When she saw that I was waiting with my son, she was kind enough to scoot over to give me some room so I could change my son. Then she asked if by any chance I had any diaper cream. I told her that I did, and the relief on her face was priceless. When she was done, she handed it back to me and I told her to keep it. I told her I could get some more where I was going. She was extremely grateful and it felt good to do something nice for a fellow mother and a little baby.
