How to Change a Diaper: A Calm Step-by-Step Guide
Updated October 2026 · 6 min read
Lay your baby on a safe, flat surface and keep one hand on them. Open the fresh diaper first, then unfasten the dirty one. Wipe front to back, lift gently by the ankles, slide the clean diaper under, and fasten it snugly with two fingers of room. Wash your hands afterwards.
- Gather everything you need before you start, and never step away from your baby on a raised surface.
- Always wipe front to back, especially for girls, to keep bacteria away from delicate areas.
- Fasten snugly but not tight: aim for two fingers of space at the waist.
- Point the belly-button stump down and fold the diaper below it until it heals.
- A little redness is common, but ask your health visitor or doctor about anything that worsens or worries you.
Set up before you start
A calm change begins with everything within reach, because you should never take your hand off a baby on a raised surface. Gather a clean diaper (called a nappy in the UK), wipes or cotton wool and warm water, a change mat or towel, a bag for the dirty one, and any barrier cream you use. If you are using a low, safe surface such as a mat on the floor, you remove the risk of a fall entirely, which many parents prefer in the early weeks.
Wash your hands first if you can, and keep the room warm. Newborns lose heat quickly and dislike feeling cold, so a cosy space makes the whole thing smoother for both of you.
Changing a wet diaper
Lay your baby on their back and open the fresh diaper so it is ready. Unfasten the wet one, fold the front down, and give the skin a gentle wipe if needed. Pat dry with a soft cloth, letting the area breathe for a moment. Slide the clean diaper under by gently lifting both ankles with one hand, then bring the front up and fasten the tabs.
- Check the fit: snug enough to prevent leaks, loose enough for two fingers at the waist.
- Make sure the leg cuffs are pulled out, not tucked in, which helps contain messes.
Changing a dirty diaper
A dirty change follows the same steps with a little more cleaning. Use the front half of the dirty diaper to wipe away the bulk of the mess, then fold it under so the clean outside is against the skin. Wipe thoroughly, always moving front to back to keep bacteria away from delicate areas. This matters especially for girls. Lift gently, remove the soiled diaper entirely, and clean any creases where mess can hide.
Early newborn poo is dark and sticky, then changes colour and texture over the first days and weeks. This is normal. Let the skin dry fully before the fresh diaper goes on.
Hygiene that protects everyone
Good hygiene keeps your baby comfortable and your home healthy. Roll the dirty diaper inward, fasten it with its own tabs, and bin or store it straight away. Wash your hands properly afterwards, every time. Wipe down the change surface regularly, and keep creams closed and out of little hands.
Common mistakes to avoid
Even confident parents slip up, usually in small ways that are easy to fix once you notice them.
- Opening the dirty diaper before the clean one is ready, which invites surprises.
- Fastening too tightly, which marks the skin, or too loosely, which leaks.
- Wiping back to front, or rushing before the skin is dry.
- Covering the umbilical stump instead of folding the diaper below it.
- Turning away for wipes left out of reach. Keep one hand on your baby, always.
Within a week or two, changes become second nature. Go gently, talk to your baby as you work, and let the rhythm settle. It will.
Frequently asked questions
How often should I change a newborn's diaper?
Newborns often need a fresh diaper every two to three hours, and whenever they have done a poo. Many parents also change before or after feeds as a natural rhythm. Trust your nose and a quick check rather than a fixed clock.
Do I need to wipe for a wet-only diaper?
A light wipe keeps skin fresh, but a soaked-only change usually needs less cleaning than a dirty one. Pat the skin dry before the new diaper goes on. Letting the area air-dry for a moment can also help.
What is the best way to prevent diaper rash?
Change promptly, clean gently, and let the skin dry fully before fastening a fresh diaper. Many parents use a thin barrier cream as a routine. If redness spreads, blisters, or does not settle, check with your health visitor or doctor.
Should I use water or wipes?
Both work. Cotton wool and warm water is a gentle choice for very new skin, while fragrance-free wipes are convenient when out. Use whichever suits your baby's skin and your routine.
What do I do about the umbilical cord stump?
Keep it clean and dry, and fold the front of the diaper down so it sits below the stump and gets air. Avoid tugging or covering it tightly. It usually dries and drops off on its own within a couple of weeks.
Why does my baby cry during changes?
Cold wipes, a chilly room, or simply disliking being still are common reasons. Warm your hands, keep the room cosy, and chat or sing to reassure them. Most babies settle as changes become familiar.
