If your baby’s heading into their first summer, welcome to a whole new season of parenting questions. New sun. New heat. New SPF debates in the aisle. Plus a rotating cast of well-meaning family telling you contradictory things about hats, hydration and “don’t forget a sweater”.
Here’s the shortlist:
1. Under 6 Months, Shade Is the Rule
The American Academy of Pediatrics (AAP) recommends babies under 6 months stay out of direct sun. Load up on stroller canopies, wide-brim hats + breathable long-sleeve onesies.
2. 6+ Months, Mineral Sunscreen Is the Move
Look for zinc oxide or titanium dioxide as the active ingredient, SPF 30+, broad spectrum, water resistant. Reapply every 2 hours + after every splash or towel-off. Skip anything with oxybenzone, octinoxate or added fragrance.
3. Babies Overheat Faster Than You Do
Babies don’t sweat as efficiently as adults, so they heat up fast. Watch for flushed skin, rapid breathing, damp hair or unusual lethargy. Get to shade or AC and offer a feed.
4. Hydration Under 6 Months = More Feeds
Babies under 6 months should only get breast milk or formula. On hot days, they may want to feed more often—that’s normal and it’s how they hydrate! Don’t offer plain water until baby’s over 6 months and started solids (and even then, small sips).
5. The Car Seat Is a Heat Trap
Never leave a baby in a parked car, even for a minute. And before you buckle in on a hot day, check the metal buckles. They can hit burn temperatures fast in direct sun. A quick swipe with the back of your hand tells you everything.
6. Bug Protection Is Physical First
For babies under 2 months, no repellent—use long sleeves, mosquito netting on the stroller, and avoid dawn + dusk outdoor time. 2 months+ can use 10-30% DEET, applied to clothing (not skin). Skip picaridin and lemon eucalyptus for babies under 3.
7. Water = Full-Time Supervision, No Exceptions
Kiddie pools, hotel pools, the beach—always within arm’s reach when a baby is anywhere near water. Inflatable “floaties” are not safety devices. The AAP recommends waiting until 12+ months for infant swim classes, and only ever with a caregiver in the water.
8. Dress Light
That “dress baby in one more layer than you’re wearing” rule is a cold-weather move, not a hot-weather one. In summer, babies do best in cotton, light colors and a wide-brim hat. Overheating is a real risk in over-swaddled or overdressed babies.
9. Room Temp for Sleep Is 68-72°F
A fan is AAP-approved! Use a lightweight cotton sleep sack (or skip it entirely) in warm rooms.
10. Traveling With Baby? Prep Like the Cooler Will Fail
Whether it’s a beach weekend or a cross-country flight, real-life prep matters—TSA rules, ice-pack timing, feeding on the go.
Numbers Worth Memorizing
→ Sunscreen SPF: 30+, reapply every 2 hours, more if there’s water involved
→ Sleep room temp: 68-72°F
→ DEET-safe age: 2 months+
→ Water in the car seat: never leave baby, always check buckle temperature
Your baby’s first summer will be sticky, sunscreen-y and full of moments you’ll want to bottle. The best move you can make? Prep for the heat and then just be present. The hat will stay on for approximately 12 seconds, someone will judge your feeding schedule at the pool and it will still be a summer they don’t remember but you always will. 🩵
