Best Newborn Summer Clothes for Your Little One

Dressing your newborn in the summer months is all about comfort, breathability, and softness. Babies are extra sensitive to heat, so finding the right newborn summer clothes can help keep them cool, safe, and stylish - all at once. Whether you're heading out for a walk or winding down for a nap, here are the best warm-weather clothing options for your baby’s first summer.

1. Baby Singlets: A Summer Essential

When it’s hot out, less is often more. Baby singlets are perfect on their own or as a base layer. They help regulate your baby's body temperature while keeping them comfortable and free to move. Purebaby’s singlets are made from soft, breathable cotton and come in multipacks - ideal for daily use.

Why We Love Them:

• Easy to layer or wear solo

• Great for day or sleep

• Soft, stretch cotton for a gentle fit

2. Lightweight Growsuits and Onesies

Short-sleeve baby onesies or growsuits are a classic in a baby summer clothes wardrobe. Our Bear Short Zip Growsuit is a must-have, made with breathable fabric and featuring two-way zips for easy changes, making it an all-in-one outfit solution. Choose lightweight baby onesies in soft cotton for maximum comfort during naps and outings.

Look for:

• Short sleeves and legs

• Two-way zip for quick changes

• Fun summer prints or soft neutrals

3. Bodysuits for Day and Night

Baby bodysuits are perfect for layering or solo wear depending on the weather. With envelope necklines and snap closures for easy dressing, they’re one of the most versatile newborn essentials you can own.

For extra softness, look for organic cotton bodysuits that are gentle on delicate skin and breathable enough for warmer days.

Handy for:

• Layering under sleeping bags at night

• Easy nappy changes on the go

• Outfits that stay put and don’t ride up

4. Accessories for Summer Days

Don’t forget a wide-brimmed hat for sun protection during outdoor time, look for options with UPF 50+ protection like our range of baby hats that combine SPF protection and comfort. A lightweight, breathable muslin wrap can also be a great addition if you're swaddling your baby - perfect for helping your newborn feel secure without overheating.

Why Breathable Fabrics Matter

Light, breathable materials like 100% organic cotton allow air to circulate and help prevent overheating. Whether you're layering a singlet or dressing your baby in a zip-up growsuit, breathable infant clothing ensures your newborn stays cool and comfy.

Hot weather tip: Always check your baby’s chest or back (not hands or feet) to see if they’re too warm. Hands and feet can often feel cool even when the rest of the body is too hot.
