How to Dress Baby in the Summer: Keeping Your Little One Cool and Comfy

Summer can be an uncomfortable time for new parents and their babies. As the temperature rises, you likely find yourself wondering how to dress your little one in the right way. Balancing comfort, safety, convenience, and style can feel like a challenge, especially when you're dealing with a little one who can't tell you if they're too hot or cold. If you’re wondering how to dress your baby in the summer, this article is for you!

Summer Baby Attire: The Basics 

When dressing your baby for summer, especially if you live in a hot climate, less is more. You want to keep your little one cool and—more importantly—protected from the sun's harsh rays. Here are some basic principles to keep in mind:

  1. Choose lightweight, breathable fabrics for baby clothes

  2. Opt for loose-fitting garments 

  3. Protect your baby’s delicate skin from sun exposure

  4. Be prepared for temperature changes from day to night 

While these are the basic principles, it can be hard to know what exactly you need to do to help your baby stay cool. Let’s consider some more specific tips you can try.

Best Fabrics for Baby Clothes in Summer

The fabric of your baby's clothes plays a crucial role in keeping them cool and comfortable. Different clothing materials also affect ventilation, sweat absorption, skin sensitivity, and overall “breathability” that you might have to consider. Summer-friendly fabric options for babies include:

  • Cotton: A natural fiber that’s breathable, light, and absorbs moisture, making it perfect for hot days.

  • Linen: Another natural fabric that's lightweight and allows thorough air circulation while on the skin. Also ideal for babies who sweat a lot.

  • Bamboo: Known for its moisture-wicking properties and hypoallergenic effects, bamboo fabric can help keep your baby dry and cool while minimizing skin irritations.

For the most part, you’ll want to avoid synthetic materials like polyester or nylon. These fabrics can retain warmth and cause your baby to overheat. Plus, they’re more likely to irritate the skin. 

Find the Comfiest Fit for Your Baby

When choosing summer outfits for your baby, prioritize loose-fitting clothes that allow air to circulate and skin to “breathe.” Loose clothing prevents heat rash and keeps your baby comfortable. Some great options include:

  • Rompers: One-piece outfits that are easy to put on and take off, typically in the form of short sleeves and shorts

  • Sundresses: Light and airy outfits for baby girls

  • Shorts and T-shirts: Simple, cool, and affordable options for your baby boy or girl

Remember, while it's tempting to dress your baby in adorable outfits, comfort should always come first in the summer months.

Clothing as Sun Protection for Babies

Babies have very sensitive skin that needs extra protection from UV and UVB sun rays. While it's best to keep your little one out of direct sunlight, especially during the hottest parts of the day, some clothing items can help when you venture outside. 

  • Wide-brimmed sun hats: Look for hats with UPF (Ultraviolet Protection Factor) for added protection

  • Lightweight, long-sleeved shirts: These can shield your baby’s arms from the sun

  • Sunglasses: If your baby will keep them on, baby sunglasses are great for protecting little eyes

Remember, clothing should be your first line of defense against the sun, followed by appropriate use of sunscreen for babies over 6 months old. As soon as your doctor recommends sunscreen for your little one, try to get them used to wearing it and make it a regular part of your outdoor routine.

Using Layers to Accommodate Temperature Changes

Summer days can consist of cool, early mornings and quickly heat up in the afternoon. Additionally, you might move between air-conditioned spaces and the outdoors frequently, exposing your baby to hot and cold temperatures repeatedly. Dressing your baby in layers allows you to adjust their clothing as needed. For example:

  • A light cardigan or jacket for cooler mornings or evenings

  • A muslin blanket for impromptu shade or an extra layer

  • Socks that can be easily removed if feet get too warm

  • A short-sleeve cotton romper and a light sweater

  • When all else fails and your baby starts to overheat, you can dress them down to their diaper and maybe a pair of comfy shorts.

Dressing Your Baby for Sleep During Summer 

Dressing your baby for sleep on warm nights requires a slightly different approach. The Sleep Foundation recommends keeping the room between 68-72°F (20-22°C) for optimal sleep conditions. Here are some tips for baby nighttime attire when it’s hot:

  • Use a lightweight sleep sack instead of a heavier swaddle

  • Dress your baby in a onesie or just a diaper if it's particularly warm in the house

  • Consider using a fan to gently circulate air in the room

Remember, overheating at night can increase the risk of SIDS (Sudden Infant Death Syndrome), so it's crucial to ensure your baby doesn't get too warm while sleeping.

Special Considerations for Newborns During Summer

Newborns require a bit more care when it comes to summer dressing. Their tiny bodies are still learning to regulate temperature, so they may need an extra layer compared to older babies. They also have yet to develop body awareness to remove garments that might become too hot. Here are some tips:

  • Use lightweight swaddles for naps and nighttime

  • Keep them in the shade as much as possible

  • Check frequently for signs of overheating, like a warm chest or neck

  • DO NOT use blankets or pillows in the crib—these can cause suffocation

  • Keep your baby properly hydrated and fed

  • Apply cool, damp cloths to your baby when they’re awake if they begin to develop a heat rash 

  • Talk with your pediatrician about any concerns you have 

Lastly, never leave your baby alone in a warm car or enclosed space (even if you think it’s not that hot). 

Signs Your Baby Might Be Too Hot

While you're figuring out the perfect summer wardrobe for your little one, it's important to watch for signs that they might be too warm! Signs include:

  • Flushed cheeks; pinkish skin 

  • Damp hair or sweating (especially at the nape of the neck)

  • Rapid breathing

  • Heat rash

  • Irritability

  • High body temperature 

  • Dry mouth or cracked lips (dehydration) 

If you notice these signs, remove a layer of clothing and take your baby to a cooler area. Offer fluids if your baby is old enough for water or extra nursing sessions for breastfed babies.

Practical Tips for Summer Baby Care

Beyond clothing, here are some additional tips to keep your baby comfortable in the summer:

  1. Stay hydrated. Offer more frequent feedings for breastfed babies or extra water for older babies (consult your pediatrician about when to introduce water).

  2. Seek shade. Plan outdoor activities for cooler parts of the day and always have a shaded spot available.

  3. Use a stroller fan. A small, battery-operated fan can help circulate air in the stroller.

  4. Lukewarm baths: A cool or lukewarm bath before bedtime can help your baby feel comfortable for sleep.

  5. Check the car seat. The straps and seat can get very hot in the sun. Check the temperature before placing your baby in the seat.

Enjoy Every Summer Milestone With Your Baby 

Dressing your baby for summer doesn't have to be complicated. By focusing on lightweight, breathable fabrics, loose fits, and sun protection, you can ensure your little one stays cool and comfortable all season long. Remember to always trust your instincts and if you're ever in doubt, it's better to dress your baby in lighter layers that you can add to if needed.

Summer is a wonderful time to make memories with your baby. From first trips to the beach to picnics in the park, these moments are precious. By keeping your baby comfortable and protected, you can fully enjoy all the joys that summer brings.
