Your Baby’s First Summer: Keeping Cool and Comfortable

Your Baby’s First Summer

KEEPING COOL AND COMFORTABLE

There’s something so special about your baby’s very first summer. The sun is shining, the days feel longer, and everything seems just that little bit more magical. But when it comes to keeping your little one cool and comfortable during those warmer days and nights, it can feel a little daunting.

Whether you’re heading out for your first family picnic or enjoying a quiet day at home, here are some practical, gentle tips to help your baby stay safe, settled and happy in the heat.


Dress Them Lightly (And Don’t Overthink It)

Babies don’t need lots of layers in summer. In fact, a short-sleeve bodysuit or a lightweight vest is often more than enough when you're indoors. Keeping things simple is best.

Made from breathable fabrics, they’re available in lightweight TOGs suitable for summer, helping your baby sleep soundly without the risk of overheating. They're also much safer than loose blankets in the cot or Moses basket.

Tip: If you’re unsure whether your baby is too warm, feel the back of their neck or chest – it’s a more accurate indicator than hands or feet.


Keep Their Sleeping Space Breezy

When it’s hot outside, keeping your baby’s sleeping space cool is essential. Aim for a room temperature between 16-20°C, and on particularly warm days, keep curtains or blinds drawn during the day to block out direct sun. You can also use a fan to help circulate air – just make sure it’s not pointing directly at your baby.

Simply dress the basket with one of our soft cotton fitted sheets to help your little one stay cool and comfortable during nap time.


Keep Baby Hydrated

Whether you’re breastfeeding or using formula, your baby may want to feed more frequently in hot weather. This is completely normal and helps them stay hydrated.

There’s no need for extra water in the first six months unless advised by a health professional - just follow your baby’s cues and offer feeds more often if they seem thirsty.


Choose Natural Fabrics

Natural fabrics like cotton and bamboo are breathable, soft and gentle on delicate skin - ideal for summer. Swap synthetic materials for lighter, airy options to avoid irritation and keep baby fresh.

Our Soft Cotton Cot Bed Sheets and Cellular Blanket are both made with natural fibres, making them perfect for light layering during nap time or when you're out and about. The blanket is especially handy to keep in your pram for shady strolls.


Protect Your Baby from the Sun

Newborn skin is incredibly sensitive, so it’s best to keep your baby in the shade and out of direct sunlight. If you’re heading outside, dress them in long, loose cotton clothing, and use a wide-brimmed hat to shield their face and neck.

You can also use a pram shade or a breathable muslin cloth draped loosely over the pushchair for added protection, but make sure air can still circulate freely.

Signs your baby might be too hot include flushed cheeks, irritability, or being unusually sleepy - if you're ever in doubt, bring them indoors and cool them down gradually.


Make the Most of the Little Moments

Your baby’s first summer is one to remember - garden naps, breezy pram walks, the sound of birds in the early morning and those soft baby sighs as they drift off to sleep in the warmth.

With just a few simple swaps and some thoughtful planning, you can make sure your little one is cool, safe and comfortable all season long.
