There was a story about a babysitter's first time using a diaper on a fussy baby. She managed to put on the diaper gently and quickly. After that, the baby calmed down. It was a positive experience as it showed that taking care of the baby's basic needs in a proper way can have a positive impact on the baby's mood.
One positive story could be when a new mother was really worried about using a diaper for the first time, but it went smoothly. The diaper was easy to put on, and the baby seemed comfortable in it right away. It gave the mother confidence in her parenting skills.
I heard a story where a father's first experience using a diaper was during a long car journey. He was afraid of leaks and mess, but the diaper held up really well. It made the journey much more pleasant for the whole family, and he realized how reliable modern diapers can be.
