How to Keep Your Baby Safe in the Summer Heat

Summer is all about sunshine, fresh air, and fun-filled adventures. But for our littlest loves, soaring temperatures can also bring serious risks. Babies are more vulnerable to heat than adults — their bodies don’t regulate temperature as well, and they can overheat quickly without showing obvious signs.

So how do you keep your baby safe, cool, and comfortable when the temperature rises?

Here are our top parent-approved tips to protect your baby from the summer heat — while keeping them comfy and cute.

1. Dress in Lightweight, Breathable Fabrics

Let’s start with the basics: what your baby wears makes a huge difference.

Choose lightweight, breathable, and natural fabrics that allow heat to escape and air to flow. Synthetic materials can trap heat and sweat, leading to overheating and skin irritation.

That’s why we always recommend organic cotton baby clothes — they’re soft, gentle on sensitive skin, and naturally temperature-regulating.

At Finn + Emma, our summer collection features:

• Short-sleeve bodysuits for maximum comfort

• Breezy rompers perfect for playtime

• Light organic footies made with 100% GOTS-certified organic cotton

They’re free from toxic dyes and chemicals, and come in prints that are just as cool as they feel.

Pro Tip: Lighter colors reflect sunlight better, so opt for white, beige, or soft pastels in the summer months.

2. Keep Baby Out of Direct Sunlight

Babies under 6 months should be kept out of direct sunlight entirely — their skin is too sensitive for sun exposure, and sunscreen isn’t typically recommended for very young infants.

If you're heading outdoors:

• Stick to shady spots (under trees, umbrellas, or canopies)

• Use a stroller with a UV-protective sunshade

• Dress baby in a wide-brimmed hat and loose clothing that covers arms and legs

For older babies (6+ months), apply a baby-safe mineral sunscreen (like zinc oxide) to small areas of exposed skin — but shade and cover-ups are still your best bet.

Remember: Even short walks can lead to sunburn or heat rash without proper protection.

 

3. Time Outdoor Activities Carefully

Avoid taking baby outside during the hottest hours of the day (typically 10 a.m. to 4 p.m.). Instead, plan stroller walks, park visits, or backyard play early in the morning or late afternoon when it’s cooler.

If you must be out during peak heat:

• Stay in well-ventilated, shaded areas

• Bring a portable fan or cooling towel

• Keep outdoor time short and sweet

Also be cautious about warm cars — even with windows cracked, the temperature inside a parked car can skyrocket within minutes.

4. Watch for Signs of Overheating

Babies can’t tell us when they’re too hot, so it’s important to know what to look for.

Common signs of overheating in babies:

• Flushed cheeks

• Fussiness or unusual sleepiness

• Rapid breathing

• Damp hair or sweating (especially at the neck or back)

• Heat rash (tiny red bumps on the skin)

If your baby shows any of these symptoms, move them to a cooler space immediately, offer fluids if appropriate, and gently remove layers of clothing.

Quick check: Touch the back of your baby’s neck. If it’s hot or sweaty, they may be too warm.

 

5. Keep Baby Hydrated (Even if They’re Not Drinking Water Yet)

Young babies shouldn’t drink water, but that doesn’t mean they don’t need extra fluids in hot weather.

If you're nursing, offer more frequent breastfeeding sessions — breastmilk naturally adjusts to keep baby hydrated. Formula-fed babies may also need more regular feeds in the heat.

For older babies (6+ months), you can offer small amounts of water between feedings. Talk to your pediatrician if you’re unsure.

6. Create a Cool Sleeping Environment

Overheating during sleep is a risk factor for SIDS (sudden infant death syndrome), so creating a cool, safe sleep space is especially important in the summer.

Tips for safe summer sleep:

• Use a fan in the room to circulate air (not pointed directly at baby)

• Dress baby in a single layer of breathable sleepwear

• Keep the room between 68–72°F (20–22°C)

• Use a fitted cotton crib sheet, and skip heavy blankets or bumpers

A breathable swaddle or sleep sack made from organic cotton can help keep baby cozy and cool at night.

7. Choose Eco-Friendly, Non-Toxic Essentials

From clothing to bedding, the products in your nursery can impact your baby’s comfort and health — especially in warmer months.

At Finn + Emma, our commitment to sustainability means you can feel confident about what touches your baby’s skin. We use:

• GOTS-certified organic cotton

• Non-toxic, eco-friendly dyes

• Ethically made, fair trade products

It’s better for baby, better for the planet, and better for peace of mind.
