What Parents Should Know
According to AAP, AAD, NIH guidelines, chlorine in pool water can irritate a baby's sensitive skin, causing dryness, redness, and rash. Babies with eczema are especially susceptible. Rinsing your baby with fresh water immediately after swimming, followed by applying moisturizer, helps prevent chlorine-related skin irritation. At 0-3 months, swimming in chlorinated pools is generally not recommended for babies under about 2 months due to infection risk and temperature regulation concerns. If you do introduce water play, keep sessions very brief and rinse skin immediately after with fresh water. It is generally considered normal when mild skin dryness after swimming that resolves with moisturizer. However, you should contact your pediatrician promptly if a widespread itchy rash with blisters or pustules after swimming in a pool, hot tub, or lake, which could be hot tub folliculitis or another infection.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Swimming in chlorinated pools is generally not recommended for babies under about 2 months due to infection risk and temperature regulation concerns. If you do introduce water play, keep sessions very brief and rinse skin immediately after with fresh water.
3-6 months
Babies can begin swimming classes from this age. Chlorine can dry out their delicate skin significantly. Apply a thin layer of petroleum jelly or barrier cream before swimming to provide some protection. After swimming, rinse immediately and apply a thick fragrance-free moisturizer.
6-12 months
With regular swimming, some babies develop recurrent dryness or rashes. The combination of chlorine and sun exposure can be especially irritating. Limiting pool time to 20 to 30 minutes and establishing a post-swim rinse and moisturize routine are the best preventive measures.
12-24 months
Toddlers who swim frequently may develop persistent dryness or eczema flares from chlorine exposure. If pool rashes are recurrent, try applying a barrier cream before each swim and consider swim shirts to reduce skin exposure. If eczema worsens significantly with swimming, discuss with your pediatrician.
What to Tell Your Pediatrician
- Describe when you first noticed pool water skin reaction in baby and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if persistent rashes or eczema flares triggered by pool swimming.
- Mention if your baby seems uncomfortable after every swim session despite preventive care.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Mild skin dryness after swimming that resolves with moisturizer
- Temporary redness that fades within hours of rinsing off chlorine
- Persistent rashes or eczema flares triggered by pool swimming
- Your baby seems uncomfortable after every swim session despite preventive care
- A widespread itchy rash with blisters or pustules after swimming in a pool, hot tub, or lake, which could be hot tub folliculitis or another infection

What You Can Do at Home
- Keep track of when you notice pool water skin reaction in baby — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild skin dryness after swimming that resolves with moisturizer — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.

Baby Rash After Swimming - Chlorine and Pool Rash
Rashes after swimming are common in babies and toddlers. Chlorine in pools can irritate the skin (especially in babies with eczema or sensitive skin), causing redness and dryness. Other causes include swimmer's itch (from lake or ocean parasites), hot tub rash (Pseudomonas folliculitis from warm water), and heat rash from being in a warm pool. Rinsing your baby with fresh water immediately after swimming and applying moisturizer is the best prevention and treatment for most post-swimming rashes.
Baby Eczema (Atopic Dermatitis)
Baby eczema is extremely common, affecting up to 20% of infants, and is not caused by anything you did wrong. It shows up as dry, red, itchy patches and is very manageable with consistent moisturizing and gentle skin care. Most children outgrow it by school age.
Baby Dry Skin & Peeling Skin
Dry and peeling skin in newborns is completely normal, especially in the first few weeks after birth. Your baby spent nine months floating in amniotic fluid, so some peeling as they adjust to the outside world is expected. Gentle, fragrance-free moisturizers applied after baths are usually all that is needed.

My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
