Washing a baby’s hands depends on their age and head control. Newborns who can’t support their heads get their hands cleaned with damp cloths, while older babies can have their hands washed under running water with your help. Either way, the goal is the same: remove germs before they end up in your baby’s mouth, which happens constantly.
Cleaning a Newborn’s Hands
Young babies who can’t hold up their heads aren’t ready for the sink. Instead, you can clean their hands using damp paper towels or soft washcloths in four steps: wet the hands with a damp cloth, wipe them down with a separate soapy cloth, rinse with another clean wet cloth, and pat dry. This method works well for babies under about three or four months, or any infant who isn’t sitting with support yet.
You don’t need to do this constantly, but it’s worth wiping down a newborn’s hands a few times a day, especially before feeding and after they’ve been grabbing at their diaper area during changes. Babies explore the world by putting their fists in their mouths, so their hands pick up and deliver germs efficiently.
Washing at the Sink for Older Babies
Once your baby has good head control and can sit with support, you can move to washing their hands under running water. Hold your baby on your hip or seat them on the counter with one arm around them. Wet both hands under lukewarm water, apply a small amount of mild soap, and gently rub all surfaces of their hands and between their fingers. Aim for about 15 to 20 seconds of scrubbing. Rinse thoroughly and pat dry.
Babies won’t cooperate perfectly with this, and that’s fine. Even a quick wash with soap and water removes far more germs than skipping it. As your baby grows into a toddler, start letting them do the motions themselves with your guidance. The CDC recommends supervising and assisting children with handwashing as needed, and for most kids, that means hands-on help well into toddlerhood.
Water Temperature and Safety
The water should feel comfortably warm, not hot. The Mayo Clinic recommends setting your water heater thermostat below 120°F (49°C) to prevent scalding. Babies have thinner skin than adults and burn more easily, so always test the water on the inside of your own wrist before putting your baby’s hands under the stream. Lukewarm is ideal.
When to Wash Your Baby’s Hands
The key moments are predictable. Wash or wipe your baby’s hands:
- Before eating or nursing, since their hands will end up in their mouth alongside food
- After diaper changes, because even if you’re the one doing the wiping, their hands wander
- After playing outside or on the floor
- After touching pets
- After being in public places like grocery stores, doctors’ offices, or playgrounds
Beyond these moments, you don’t need to wash obsessively. Too-frequent washing can actually damage your baby’s skin, leading to dryness and cracking that creates its own problems.
Choosing the Right Soap
Regular soap is alkaline, with a pH around 10, which can disrupt the natural acid layer that protects a baby’s skin. For babies, a mild liquid cleanser that is unscented and neutral to slightly acidic (pH 5.5 to 7) is a better choice. Look for products labeled “gentle” or “sensitive” rather than standard hand soap. Avoid antibacterial soaps unless your pediatrician specifically recommends one.
A European panel of skin care experts has recommended that baby cleansers contain no known irritants and have minimal effect on the skin’s surface. If your baby has eczema or very dry skin, you may want to skip soap on their hands entirely for routine washes and use plain water, reserving a mild cleanser for times when their hands are visibly dirty.
Hand Sanitizer and Babies
Soap and water is always the better option for babies. Hand sanitizer contains alcohol, which can sting dry or cracked skin and poses a swallowing risk for young children who put their hands in their mouths. If you do use sanitizer on an older baby or toddler in a pinch (like when you’re out and there’s no sink available), apply a small amount and rub it in completely. Keep the bottle out of reach, and supervise closely until it dries. The CDC specifically warns about supervising young children with hand sanitizer to prevent them from ingesting the alcohol.
Protecting Your Baby’s Skin
Frequent hand washing can strip moisture from a baby’s already delicate skin. The simplest prevention step is choosing a moisturizing soap and applying a cream (not a lotion) to your baby’s hands right after washing. Creams are thicker and form a better moisture barrier than thinner lotions. Applying the cream while the skin is still slightly damp helps trap that moisture in.
If your baby’s hands start looking red, dry, or cracked despite using a gentle soap, try switching to a petroleum-based ointment instead of cream. For persistent dryness, applying ointment at bedtime and covering the hands with soft cotton socks overnight can intensify the moisturizing effect. If none of that helps after a few days, a small amount of over-the-counter hydrocortisone cream is the next step before checking in with your pediatrician.
Building the Habit as They Grow
Around 12 to 18 months, most toddlers can start participating in handwashing with your help. Let them feel the water, rub their palms together, and play with the soap foam. Singing a short song or counting together makes the 20-second scrub feel less like a chore. The goal at this stage isn’t perfection. It’s making handwashing feel normal and routine so that by the time they’re in preschool, the habit is already second nature.
For toddlers, a step stool at the sink and a faucet extender (a simple silicone piece that brings the water stream closer to little hands) can make the process easier and safer. Keep helping them scrub between fingers and the backs of their hands, since kids tend to just rub their palms together and call it done.
