Diapers, Bathing, and Keeping Things Clean
New babies come with a surprising amount of wiping, washing, and rinsing, and it is completely normal to feel unsure at first. This guide walks through the everyday clean-up jobs — diapers, the umbilical cord stump, baths, bottles, and hands — using guidance from the American Academy of Pediatrics (AAP) and the CDC. It is information, not medical advice; your own pediatrician is always the right person to ask about your baby.
01Diaper changes, step by step
-
Set up before you unsnap anything: have a fresh diaper, wipes, and a change of clothes within arm's reach so you never have to step away from your baby.
The AAP recommends keeping diapering supplies within your reach — but out of your child's reach — so you don't have to leave your baby's side mid-change.

Never leave your baby unattended on a changing table — even for a moment, even buckled in.
The AAP is direct about this: use the safety strap, but don't depend on it alone to keep your child secure. A hand on your baby beats any buckle.

Expect a lot of changes at first — many new parents go through 8 to 12 diapers a day in the early stretch.
The AAP notes it averages out to about six changes a day across the diaper-wearing years, so the newborn weeks are the peak. Stashing supplies in more than one spot around the house (and in the car) saves a lot of trips.

Wash your hands with soap and water after every diaper change.
The CDC lists 'after changing diapers' as one of the key times to wash hands — scrub for at least 20 seconds.

02Keeping diaper rash away
-
The best prevention is simple: change wet or dirty diapers promptly and keep the skin clean and dry.
MedlinePlus (the National Institutes of Health's health information service) advises changing your baby's diaper often, and as soon as possible after the baby urinates or passes stool.

Give the diaper area some open-air time when skin looks irritated.
MedlinePlus suggests laying your baby on a towel without a diaper when possible — the more time out of a diaper, the better for irritated skin.

A thick layer of barrier paste — a protective cream made with zinc oxide or petroleum jelly — at changing time helps shield skin from moisture.
The AAP also suggests fragrance-free wipes (or plain water and a gentle cleanser), absorbent diapers, and a slightly loose diaper fit, especially overnight.
Source: AAP (HealthyChildren.org) -
Call your pediatrician if a rash is not improving after 2 to 3 days, has blisters, pimples, or pus-filled sores, comes with a fever, or shows up in your baby's first 6 weeks.
These are the specific call-the-doctor triggers MedlinePlus lists for diaper rash.

03The umbilical cord stump
-
Keep the stump clean and dry until it falls off on its own — typically by about 3 weeks.
The AAP says there's no need to put alcohol on the stump. Folding the top of the diaper down below the cord keeps urine from soaking it.
Source: AAP (HealthyChildren.org) -
Stick to sponge baths until the stump falls off.
MedlinePlus notes the stump usually dries and drops off when a baby is roughly 5 to 15 days old, and recommends cleaning around it with plain water and keeping bath time to sponge baths until then.
Source: MedlinePlus (NIH) -
A few drops of blood on the diaper around the time the stump falls off are normal.
The AAP says this small amount of dried blood is expected and not a cause for alarm.
Source: AAP (HealthyChildren.org) -
Some things are worth a call: foul-smelling yellowish discharge, red skin around the base, a baby who cries when the cord area is touched, or a stump still attached past 3 weeks — call your pediatrician. Active bleeding that keeps coming needs immediate care.
These are the warning signs the AAP lists for the cord stump.

04Bath time, without the guesswork
-
A few baths a week is genuinely enough — the AAP says about three baths per week may be all your baby needs during the first year.
Bathing more often than that can dry out a newborn's delicate skin.
Source: AAP (HealthyChildren.org) -
Use only about 2 inches of water, and make sure it feels warm — not hot — tested on the inside of your wrist or elbow.
Those spots are more sensitive to heat than your hands, so they're a better thermometer.
Source: AAP (HealthyChildren.org) -
Set your home's water heater so the hottest tap water tops out at 120°F.
This is the AAP's anti-scald recommendation — hotter tap water can cause serious burns on baby skin very quickly.
Source: AAP (HealthyChildren.org) -
Never leave your baby alone in the water, even for an instant — keep a hand on your baby the entire time.
The AAP notes that most young-child drownings at home happen in bathtubs, more than half involving babies under a year old. If the phone or doorbell demands you, the baby comes with you.

05Washing bottles and pump parts, the CDC way
-
Wash your hands, take the bottle completely apart (nipple, ring, cap, any valve), and wash the pieces in a dedicated basin — not directly in the sink.
The CDC recommends a wash basin and bottle brush used only for baby feeding items, because sink drains can harbor germs. Scrub with hot, soapy water and squeeze soapy water through the nipple holes, then rinse well.
Source: CDC -
Let everything air-dry completely on a clean, unused dish towel or paper towel — don't rub or pat items dry.
Toweling can transfer germs right back onto clean parts, per the CDC.
Source: CDC -
Sanitize feeding items daily if your baby is under 2 months old, was born prematurely, or has a weakened immune system.
A dishwasher run with hot water and a heated drying cycle handles cleaning and sanitizing in one go, per the CDC. For older, healthy babies, daily sanitizing may not be needed if items are cleaned carefully after each use.
Source: CDC -
For breast pump parts: wash your hands before pumping, inspect the kit, then rinse and wash every piece that touches milk as soon as possible after each session, and let the parts air-dry.
The CDC adds that pump tubing doesn't need routine washing if milk never touches it — but if you ever see milk or mold inside the tubing, replace it rather than trying to clean it.

06Hands and visitors
-
The CDC's handwashing basics: scrub with soap and water for at least 20 seconds, especially after diaper changes, after coughing, sneezing, or blowing your nose, and before preparing or eating food. No soap nearby? A hand sanitizer with at least 60% alcohol works.
The CDC calls handwashing one of the most effective ways to prevent the spread of germs.
Source: CDC -
It's okay to ask visitors to wash their hands — and to ask sick friends and family to wait until they're well before meeting the baby.
The AAP's 'cocooning' guidance asks relatives to practice good hygiene like hand washing, to let you know when they're sick and return only once well, and to skip kissing or getting close to the baby when coughing or possibly sick.
Source: AAP (HealthyChildren.org) -
Ask the adults who will be around your newborn regularly to be up to date on flu and whooping cough (Tdap) vaccines.
The AAP recommends household members and caregivers be current on these — ideally at least 2 weeks before visiting — because newborns are too young to get some vaccines themselves.

07Baby laundry, simply
-
Wash new clothes, blankets, and anything else that will touch your baby's skin before the first use.
New fabric can carry residues from manufacturing and shipping; one wash takes care of it.
Practical suggestion - A gentle, fragrance-free detergent is a sensible default, and a separate baby-only load usually isn't necessary — if your baby's skin seems irritated by laundry, ask your pediatrician. Practical suggestion
