How to Change a Diaper: A Step-by-Step Guide

Changing a diaper takes about a minute once you have done it a few times, and the whole thing comes down to one non-negotiable rule: never take your hand or your eyes off your baby on a raised surface. Everything else is technique you will have down by the end of the first week.

You will do this thousands of times, so it is worth getting the small things right early: the order of operations, how to prevent rash, and how to read what is in the diaper, which in the newborn weeks is one of the best signals that feeding is going well.

Here is the full step by step, plus how often to change, how to handle the cord stump, and when a rash needs a doctor.

What You Need and the One Safety Rule

Have everything staged before you start. The moment you need to reach for a wipe on the far shelf is the moment a wriggle turns into a fall.

How to Change a Diaper, Step by Step

1. Gather your supplies. Clean diaper, wipes, barrier cream, and a spare outfit, all within arm’s reach.¹
2. Lay your baby down and keep a hand on them. A changing mat on the floor or a firm surface. Hand stays on your baby throughout.²
3. Open the diaper and use it. Unfasten the tabs, and for a messy one, use the clean front of the diaper to wipe away the bulk before folding it closed under your baby.
4. Clean front to back. Wipe thoroughly, always front to back, and get into the leg creases. For girls this direction matters to keep bacteria away from the vagina and urinary tract.⁴
5. Let the skin dry, then protect it. Pat dry or let it air a moment, then apply a thin layer of zinc oxide or petrolatum barrier cream if the skin looks irritated.⁶
6. Fasten and check the fit. Slide a clean diaper under, bring it up snug, and fasten so the tabs are even with no gaps at the hips. Pull the leg ruffles out to prevent leaks, and do not fasten too tight.¹
7. Wash up. Wash your hands, and your baby’s, with soap and water.³

For a newborn, fold the front of the diaper down so it sits below the umbilical cord stump, keeping the stump clean and dry until it falls off, usually within about three weeks.⁵

How Often to Change a Diaper

Newborns go through a lot of diapers. The AAP notes a newborn may urinate as often as every one to three hours, which can add up to 8 to 12 changes a day once you find your rhythm.¹ Change whenever the diaper is wet or soiled, and always before or after feeds so you are checking regularly.

What is in the diaper is also a health signal in the early weeks. A well-fed newborn should have six or more wet diapers a day, with pale or nearly colorless urine, by 5 to 7 days old.⁷ The CDC flags fewer than 6 wet diapers and fewer than 3 stools a day by day 5 as a reason to check in with your pediatrician or a lactation consultant.⁸

How Broken Newborn Nights Really Are

Those overnight changes are part of a genuinely broken newborn night for most families. In our State of Baby Sleep 2026 report, a survey of 74,379 parents across 112 countries, frequent waking is the newborn norm.

48.8 percent of babies aged 0 to 3 months woke three or more times a night, and 31 percent of newborns had a bedtime after 9pm. If you feel like you are changing diapers around the clock, you basically are, and it is normal.

Preventing and Spotting Diaper Rash

Some irritation from wetness and friction is common and usually clears with basic care: change frequently, clean gently, let the skin air-dry, and apply a thick layer of barrier paste with zinc oxide or petrolatum.⁶ A little time with the diaper off helps too.

Those signs can point to a bacterial or yeast infection that needs treatment rather than more cream.⁶

What the Products Do and Do Not Do

Two honest notes on the aisle full of diapering products. First, skip baby powder. The AAP advises against it: talc-based powder can contain asbestos fibers and inhaling the fine powder can cause serious lung problems, and even cornstarch powder carries a respiratory-irritation risk if breathed in.⁹ There is no version of baby powder that is worth that risk on a diaper.

Second, cloth versus disposable is a personal and budget choice, not a rash question. The AAP states there is no current evidence showing which type does a better job of preventing diaper rash.⁶ And “hypoallergenic” or “natural” wipe labels are not regulated to any federal standard, so treat those claims as marketing rather than proof. Frequent changes and a good barrier cream do more than any premium label.

Diapering is one of the first newborn skills you master, alongside safe swaddling. Before long you will be chasing a baby who is on the move, so our guide to when babies crawl is worth a bookmark for what comes next.
