Changing a newborn's diaper safely involves preparing the necessary supplies, cleaning the diaper area gently, allowing the skin to dry, and securing a clean diaper comfortably. Newborns generally need frequent diaper changes, particularly after bowel movements, to reduce prolonged exposure to urine and stool. During the early weeks, parents should take care around the umbilical cord stump and use a diaper that does not rub against or cover the area unnecessarily. A newborn should always be kept within reach during diaper changes and should never be left unattended on a changing table or other elevated surface. Regular changes, gentle hygiene, and appropriate skin care can help reduce irritation and diaper rash. If the baby develops persistent redness, sores, swelling, discharge, or other unusual skin changes, parents should consult a paediatrician or healthcare professional.
