Sunscreen for Babies - When and How to Use It
The short answer
The AAP recommends keeping babies under 6 months out of direct sunlight entirely and using protective clothing and shade instead of sunscreen. For babies 6 months and older, use a broad-spectrum, SPF 30+ mineral (zinc oxide or titanium dioxide) sunscreen on all exposed skin. Apply 15-30 minutes before sun exposure and reapply every 2 hours or after swimming/sweating. For babies under 6 months, if sun exposure cannot be avoided (no shade available), a small amount of mineral sunscreen on exposed areas (face, backs of hands) is acceptable as an exception.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-12 months
For babies under 6 months, the primary sun protection strategy is avoidance and clothing: keep babies in the shade, use a stroller canopy or umbrella, dress in lightweight long sleeves and pants, use a wide-brimmed hat, and avoid the peak sun hours (10 AM - 2 PM). If you cannot keep your baby in the shade, it is acceptable to apply a small amount of mineral sunscreen (zinc oxide or titanium dioxide) to exposed areas like the face and backs of hands. After 6 months, apply mineral sunscreen liberally to all exposed skin. Choose fragrance-free, mineral-based formulas designed for babies. Test a small patch first if your baby has sensitive skin or eczema.
1-3 years
Apply broad-spectrum SPF 30+ mineral sunscreen to all exposed skin 15-30 minutes before going outside. Reapply every 2 hours and immediately after swimming, sweating, or toweling off. Do not forget commonly missed areas: ears, back of neck, tops of feet, and around the eyes. Stick-type sunscreens work well for the face. Continue to use protective clothing and hats as the primary defense, with sunscreen as an additional layer. Avoid spray sunscreens for the face (inhaling the spray is a concern) - spray on hands first, then apply to the face. Choose "water-resistant" formulas for swimming (no sunscreen is truly waterproof).
What Should You Do?
When to take action
- Mild white residue from mineral sunscreen on the skin
- Your baby not enjoying the sunscreen application process (common in toddlers)
- Needing to reapply frequently during outdoor activities
- Your baby had a reaction (rash, redness, or irritation) to a sunscreen product
- You want guidance on sun protection for a baby with eczema or very sensitive skin
- Your child got sunburned despite sunscreen use and you want guidance on treatment and prevention
- Severe sunburn with blistering on a baby or toddler
- Signs of sun poisoning: severe sunburn with fever, chills, nausea, or headache
- Sunburn on a baby under 6 months (their skin is more vulnerable to damage)
- An allergic reaction to sunscreen with hives or facial swelling

Related Medical Concerns
Essential First Aid Kit for Baby and Toddler
Every family with a baby or toddler should have a well-stocked first aid kit. Essential items include: a digital rectal thermometer (most accurate for babies), infant acetaminophen (Tylenol), infant ibuprofen (for 6 months+), saline nasal drops, a nasal aspirator/NoseFrida, antibiotic ointment (bacitracin), petroleum jelly, hydrocortisone cream (1%), adhesive bandages, gauze and medical tape, a dosing syringe (not a kitchen spoon), Poison Control number (1-800-222-1222), and your pediatrician's after-hours number. Keep medications locked away from children and check expiration dates regularly.
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 Heat Rash (Prickly Heat / Miliaria)
Heat rash happens when sweat gets trapped under your baby's skin, causing tiny red bumps or blisters, usually in skin folds or areas covered by clothing. It is harmless and clears up quickly once your baby is cooled down. Dressing your baby in one layer more than you would wear is a good rule of thumb to prevent overheating.
My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
