Final answer:
Ensure newborn safety by placing them in a secure environment and never leaving them unattended while gathering diapering supplies. Always keep a hand on the baby if they are on an elevated surface.
Step-by-step explanation:
When you have an experienced newborn, safety is of the utmost importance, especially when it's time to change their diaper. Before gathering supplies for diapering, make sure the baby is placed in a secure and safe environment, such as a crib or on a changing table with raised sides, and never leave them unattended even for a moment.
Always have one hand on the baby if they are on a raised surface to prevent any accidents. If you need to move away from the baby's immediate vicinity, it is wise to carry them with you or ensure they are in a secure location, like a playpen, where there is no risk of falling or encountering any hazards.
