The basic steps for changing a diaper

Changing a diaper takes about five minutes once you know the sequence. Gather your supplies first—a clean diaper, wipes, and a diaper cream if you use one—so you are not hunting for them while your baby is on the changing surface. Lay your baby on a flat, safe surface like a changing table or bed, never leave them unattended, and keep one hand on them at all times.

Unfasten the tabs on the sides of the dirty diaper, fold the front down, and wipe your baby from front to back with a wipe. For boys, wipe the genital area and the creases of the thighs. For girls, always wipe from front to back to avoid spreading bacteria. Lift your baby's bottom by gently raising their legs, slide the dirty diaper out from underneath, and set it aside.

Slide the clean diaper under your baby's bottom so the back edge is at waist level. Bring the front up between their legs, pull the tabs snug but not tight, and fasten them on both sides. The diaper should fit snugly enough that you cannot fit more than one finger under the waistband. If the leg cuffs are folded inward, pull them out so they sit against your baby's skin—this prevents leaks.

Key Takeaways

  • Gather all supplies before you start so you never leave your baby unattended on the changing surface.
  • Always wipe from front to back, especially with girls, to prevent bacterial infection.
  • Fasten the tabs snugly but not so tight that you cannot fit a finger under the waistband.
  • Pull the leg cuffs outward so they sit flat against your baby's skin rather than folded inward.
  • Wash your hands after every diaper change to reduce the spread of bacteria and viruses.

Setting up a safe changing space

A changing table, dresser with a pad on top, or even a bed works as a changing surface as long as it is stable and at a comfortable height for you. Pad it with a waterproof changing pad or a folded towel so moisture does not soak through. Keep a small trash can or diaper pail within arm's reach so you can dispose of the dirty diaper without stepping away.

Stock your changing area with a container of wipes, a stack of clean diapers, diaper cream, and a change of clothes. Some parents keep a small spray bottle of water nearby to dampen wipes for newborns, since commercial wipes can irritate very young skin. Never turn your back on your baby or reach for something across the room—if you need something you do not have, take your baby with you or wait until someone else can hand it to you.

Choosing the right diaper size and fit

Diaper sizes are based on weight, not age. A newborn typically wears size Newborn or size 1, but check the weight range on the package—it varies by brand. As your baby grows, you will move up a size when the current size starts leaking regularly or when the tabs no longer reach comfortably across your baby's belly.

A properly fitting diaper has the waistband sitting at or just below your baby's belly button, and the leg cuffs should form a seal around the thighs without leaving red marks. If you see leaks at the legs, the diaper may be too small. If the tabs overlap significantly or the diaper sags, it may be too large. Some babies fall between sizes during growth spurts, so you may need to use two sizes for a few weeks.

Dealing with blowouts and diaper rash

A blowout happens when stool leaks out of the diaper and onto your baby's clothes and skin. This usually means the diaper is too small, the leg cuffs are folded inward, or your baby has very loose stools. Change the diaper as soon as you notice it, rinse your baby's skin with warm water, pat dry, and explore a clean diaper. If blowouts happen frequently, try the next size up or a different brand—some babies fit certain shapes better than others.

Diaper rash is red, irritated skin in the diaper area. It develops when skin stays wet or in contact with stool for too long. Change diapers frequently, especially after bowel movements, and let your baby's skin air-dry for a few minutes before putting on a fresh diaper. A diaper cream with zinc oxide or lanolin creates a moisture barrier and can prevent or soothe mild rash. If the rash does not improve in three days, spreads, or your baby develops blisters or pustules, contact your pediatrician—it may be a yeast infection or bacterial infection that needs treatment.

Diaper changes on the go

Portable changing pads fold into a compact square and fit in a diaper bag. They have a waterproof backing so you can lay them on a bathroom counter, car seat, or park bench. Keep a small pack of wipes, a few diapers, and a small trash bag in your diaper bag so you can change your baby anywhere without searching for supplies.

In public restrooms, use the changing table if one is available. If not, lay your portable pad on the bathroom counter or, if your baby is older and can sit up, change them while they sit on your lap. Bring hand sanitizer or wet wipes for your own hands if soap and water are not available. Wash your hands as soon as you reach a sink, even if you used sanitizer.

When to call a pediatrician

Contact your pediatrician if your baby has not had a wet diaper in over eight hours, if their stool is consistently hard or pellet-like, or if they have diarrhea that lasts more than a few days. These can signal dehydration or digestive issues that need medical attention.

Also reach out if your baby develops a rash that does not improve with frequent changes and diaper cream, if the rash spreads beyond the diaper area, or if your baby seems to be in pain during diaper changes. Severe diaper rash, signs of infection, or unusual stool color or consistency are reasons to call rather than wait for a scheduled appointment.

Frequently Asked Questions

How often should I change my baby's diaper?

Newborns need a diaper change every two to three hours or whenever they soil it, which can be eight to twelve times a day. Older babies may go longer between changes, but you should change them after every bowel movement and whenever the diaper feels wet. Leaving a baby in a wet or soiled diaper for extended periods increases the risk of diaper rash.

Can I use regular wipes on a newborn?

Commercial baby wipes are safe for most newborns, but some have fragrance or alcohol that can irritate very sensitive skin. If your newborn has redness or irritation, try wipes labeled fragrance-free and alcohol-free, or dampen cotton pads with warm water instead. After the first month, most babies tolerate standard baby wipes without issue.

What should I do with a dirty diaper?

Disposable diapers go in a regular trash can or a diaper pail, which is a small trash can designed to contain odor. Tie the diaper in a knot or wrap it in a plastic bag before throwing it away to reduce smell. If you use cloth diapers, rinse out solid waste in the toilet first, then store the diaper in a wet bag until wash day.

Is diaper cream necessary?

Diaper cream is not necessary for every baby, but it helps prevent rash by creating a moisture barrier between skin and urine or stool. If your baby has never had rash, you may not need it. If your baby is prone to rash or has sensitive skin, explore a thin layer of cream at each change can prevent problems before they start.

How do I know if the diaper is too tight?

A diaper that is too tight leaves red marks on your baby's skin, restricts their movement, or causes them to cry when you fasten it. The waistband should sit comfortably at or below the belly button, and you should be able to fit one finger under the waistband without forcing it. If you see marks that do not fade within a few minutes, loosen the tabs slightly or move to the next size up.
