Caring for a newborn during a Texas summer brings unique challenges. High temperatures, intense sun, and humid conditions can pose serious risks to infants under six months, who are more vulnerable to overheating and dehydration. At Arlington Prime Pediatrics, we’re committed to helping you navigate your baby’s first summer with confidence and care.
This guide offers evidence-based tips—aligned with recommendations from the American Academy of Pediatrics (AAP)—to keep your newborn safe, comfortable, and healthy during the warmest months of the year.
1. Avoid Direct Sunlight Whenever Possible
Infants under six months should be kept out of direct sunlight entirely. Their delicate skin is highly sensitive to UV rays and can burn quickly, even on cloudy days.
- Stay indoors between 10 AM and 4 PM, when the sun is strongest
- Use shaded areas: strollers with canopies, tree cover, or umbrellas
- Dress your baby in lightweight, breathable clothing that covers arms and legs
2. Skip the Sunscreen (If Under 6 Months)
The AAP advises against using sunscreen on babies younger than six months. Instead, prioritize protective shade and clothing.
If sun exposure is unavoidable:
- Apply a small amount of mineral-based sunscreen (SPF 30 or higher) to small areas such as the nose or back of hands
- Use baby-safe formulas with zinc oxide or titanium dioxide
For babies over six months, consistent sunscreen use becomes more appropriate. Learn more at HealthyChildren.org.
3. Prioritize Hydration (Even If Breastfeeding)
Young babies are at risk of dehydration, especially in the heat. Newborns can’t express thirst, so caregivers need to watch for signs.
Dehydration signs in newborns:
- Fewer than six wet diapers in 24 hours
- Dry mouth or cracked lips
- Irritability or unusual drowsiness
Feeding guidelines:
- Breastfed infants may feed more often for hydration; no water is needed unless directed by a pediatrician
- Formula-fed infants should follow their regular feeding schedule
- Do not offer plain water to babies under six months without medical approval
Use this hydration guidance from the CDC as a reference.
4. Keep the Indoor Environment Cool
Newborns can’t regulate their temperature well. It’s important to maintain a comfortable indoor space during the hottest hours.
Simple home cooling strategies:
- Use fans and air conditioning when possible
- Keep blinds or curtains closed to block out sunlight
- Dress your baby in one layer of light cotton clothing inside
- Avoid overdressing or wrapping in heavy blankets
5. Never Leave a Baby in a Car—Even for a Minute
This one is critical: never leave your baby in a parked car, even with the windows cracked. The interior temperature can spike by 20 degrees in just 10 minutes, creating life-threatening conditions.
Make it a rule:
- Always check the backseat before locking the car
- Keep a visual reminder near your keys or on your dashboard
- Ask caregivers to confirm safe drop-offs or pickups

6. Watch for Signs of Overheating
Getting fresh air is beneficial, but summer outings must be carefully timed.
Tips for safer outdoor time:
- Go for walks early in the morning or after 6 PM
- Choose shaded parks or tree-lined sidewalks
- Use a stroller with ventilated mesh and a sun canopy
- Pack extra outfits, wipes, and muslin cloths
- Keep outings short—especially if temperatures rise unexpectedly
