Experts now say protecting kids’ skin barrier matters more than sticking to a daily scrub. Here’s how often children really need a bath at every age.

Updated guidelines from both Canadian dermatologists and the American Academy of Pediatrics recommend short baths using mild cleansers—and only when needed. They also suggest applying moisturizer immediately after. Recent studies show that infants who were bathed often were more likely to have skin barrier dysfunction.

This means that the skin’s natural shield isn’t keeping moisture in and irritants out, and can lead to dryness and irritation.

Whether a nightly bath is a part of your child’s bedtime routine or you also wait to see dirt, here’s what you need to know.

Your kid’s skin is likely more sensitive than yours

According to the Toronto Dermatology Centre, studies show that young kids have softer, thinner, and more sensitive skin than adults, which can be easily irritated and prone to moisture loss. This can put them at greater risk of skin issues like eczema, which over-showering can exacerbate.

Frequent bathing, especially with harsh soaps or hot water, can strip natural oils away, disrupting the skin’s protective barrier. It’s important to remember that kids don’t need to be sterilized and that some exposure to microbes is beneficial for immune development.

While every child is different, as a general rule, bathing or showering once every two to three days is fine—at least before they hit puberty, said Dr. Benjamin Barankin, the medical director and founder of the Toronto Dermatology Centre.

Bathing toddlers (1-3 years)

We all know that toddlers are much more active and prone to getting dirty from play, food and outdoor activities, which might warrant more frequent baths. Three to four baths per week should be enough, or daily if they are very active, sweat a lot, or have visible dirt.

This is an opportunity to make bath time a fun and consistent part of their routine, which can aid in sleep and relaxation. Incorporate bath toys and mild bubble bath. Continue to use gentle products and avoid prolonged exposure to hot water.

Bathing preschoolers and older children (3+ years)

As children enter preschool and school, their exposure to germs and physical activity increases, potentially leading to a need for more frequent bathing. Daily bathing might become more common, especially after sports, outdoor play, or if they start to develop body odour (typically around pre-puberty).

This is when you want to instil proper hygiene habits, such as washing their armpits, groin and feet. Again, use mild soaps and moisturizers, especially for children with sensitive skin or eczema.

Reasons for more frequent baths

Some children may need to bathe more often due to lifestyle, environment, or health factors:

• Active kids: Sports, outdoor play, and heavy sweating can call for daily baths.
• Climate: Hot, humid weather may require more frequent bathing to prevent heat rash, while cold, dry climates often call for less to avoid skin dryness.
• Skin conditions: Children with eczema or other skin issues may need tailored routines—such as shorter baths, specific cleansers, and immediate moisturizing.
• Family preference: Some families build daily baths into bedtime or morning rituals, which is fine if gentle products are used and skin health is monitored.

The soap-free benefits of bath time

Bathing isn’t just about getting clean, it plays an important role in family routines and child development:

• Helps establish bedtime rituals that support better sleep.
• Creates a relaxed environment for parent–child bonding and conversation.
• Supports sensory development through the feel of water, bubbles and toys.
• Provides opportunities to teach concepts like body parts, washing and water safety.
• It can be soothing for fussy or overstimulated children.

Essential bath time practices for healthy skin

To keep baths gentle and skin-friendly:

• Use lukewarm water (test with your wrist or elbow) to avoid burns and dryness.
• Limit baths to 5–10 minutes.
• Pat skin dry and moisturize within three minutes to lock in hydration.
• Never leave a child unattended, even briefly, and keep all supplies within reach.

When choosing bath and skincare products, look for those that are:

• Fragrance-free or unscented
• Gentle on skin
• Free of common allergens
• Do not clog pores

The Canadian Dermatology Association recognizes a small list of products that meet this criterion. Cerave Baby Lotion and Cerave Baby Wash and Shampoo are the only baby products on the list.

This doesn’t mean that only these products are safe for your kids, but it’s a good place to start.

Signs your child might need more or fewer baths

• Fewer baths may help if baby’s skin is dry, flaky, itchy, red, or if eczema symptoms worsen.
• More baths may help if there’s persistent body odour, visible dirt, or rashes in skin folds.
• Observe and adjust to your child’s individual needs—balance is key.
• Some parents find flexible routines work best, such as designated bath days or child-chosen “no shower” days.

When to consult a healthcare professional

Seek medical advice if you notice:

• Persistent or worsening rashes.
• Signs of infection, such as pus, fever, or spreading redness.
• Ongoing concerns about your child’s skin health or reactions to bathing.

The bottom line

There’s no one-size-fits-all answer to bath frequency, and it largely depends on age, activity, and individual skin needs. The rules that apply to all bathers are: use gentle products, lukewarm water, and immediately moisturize for healthy skin. Always prioritize skin health over the notion of daily scrubbing, especially for younger children. See what your child’s unique needs are and adjust their bathing routine accordingly.
