Summer Baby Care: Heat Safety, Hydration & Sun Protection Guide

Heat Safety Rules

Never leave a baby in a parked car — even for a minute. Car interior temperatures can reach 120°F+ in 10 minutes. Dress baby in light, loose clothing. Keep indoor temperature at 68-72°F. Watch for signs of overheating: flushed red skin, rapid breathing, fussiness, lethargy, and hot skin without sweating.

Sun Protection

Babies under 6 months should stay out of direct sunlight. Use shade, wide-brimmed hats, and UPF 50+ clothing. For babies 6+ months, use SPF 30+ mineral sunscreen (zinc oxide or titanium dioxide). Apply 15 minutes before sun exposure, reapply every 2 hours. Avoid peak sun hours (10 AM-4 PM). UV-blocking stroller covers provide mobile shade.

Hydration Guidelines

Under 6 months: breast milk or formula provides all needed hydration — offer more frequent feeds in hot weather. Do NOT give water to babies under 6 months (risk of water intoxication). After 6 months: small sips of water with meals (2-4 oz/day). Watch for dehydration: fewer wet diapers, dark urine, dry mouth, no tears, sunken fontanelle.
