Summer Sleep Sacks for Babies and Toddlers

Sleep Better in Our Baby Summer PJs

When the temperature creeps up, getting a solid night's sleep can feel like a battle for bedtime but having a quality, TOG rated summer sleep sack or summer sleeping bag will be your best defence against losing sleep in the warmer months. Designed to be thinner and lightweight, a summer sleep sack or summer specific swaddle will help keep your baby cool and prevent overheating, for longer and more comfortable sleep.

To make dressing your baby simple, we use TOG ratings which stands for Thermal Overall Grade. TOGs are used to define how much warmth a sleep bag offers and the higher the grade (ie 2.5 -3.5 tog) the thicker and warmer your baby will be. In summer or warmer conditions, a 0.2 tog or 1.0 tog is your best bet. For temperature-controlled climates such as air conditioning, adding a lightweight layer is best but always reference a tog guide for the most relevant safe sleep dressing guidelines.

For a touch of extra sleep assurance, offering your baby the ability to sleep in a more natural Arms Up position can do wonders for sleep for the whole family. Our Swaddle Up™ and Swaddle Up™ Transition Bag feature unique patented wings that allow babies access to their hands, so they can gently rub their face like they did in the womb and self soothe between sleep cycles. This can help promote longer, more restful sleep for them, and for you.

Summer Sleepwear That Grows With Your Child

As your little one gets older, their needs change, and their sleepwear should too! That's why we’ve created designs that grow right along with them, perfect for those transitioning age groups. Once your baby starts showing signs of rolling, it's time to move on from swaddling and transiton to arms free sleep for safety. Our innovative Swaddle Up™ Transition Bag includes removable zip on-zip off wings, which allows for a gentle, graduation to arms-free sleeping without an abrupt and unexpected disruption to everyones sleep.

We know comfort is key, especially in the heat! Our Dreamstretch Bamboo collection is crafted from a soft, lightweight bamboo fabric that feels buttery soft and is perfect for delicate skin. It's naturally moisture-wicking properties and breathable fibres keeping babies dry and comfortable all night long. Our sleepwear goes through extensive quality and performance testing, so you can trust they hold up wash after wash. They are completely washing machine and dryer friendly, making your laundry life that much easier, so you can get back to the baby snuggles.

Stay Cool for Many Summers to Come

Choosing the right summer sleeping bag baby is simple when you consider our three distinct developmental “stages” of sleepwear. Each stage is perfectly suited for a specific phase of your baby’s development and are all available in lightweight TOGS, ensuring they always have the safest and most comfortable sleep environment. The Stage 1 Swaddle UP™ is ideal for newborns who love to be swaddled, but want to acces their hands to their face, like they did in the womb to be able to self-soothe. Our Stage 2 Swaddle Up™ Transition Bags or Suits features zipper-removable wings, designed to help babies transition safely and gently to arms free sleep and should be used when they start showing signs of rolling. For when they outgrow stage 2 and are ready to get on the move, Stage 3 Sleep Bags or Suits provides a safe, wearable blanket option for older infants and toddlers who are fully rolling and active in the crib. We provide clear sizing and age guides to help you choose the correct product, which is based more on your baby’s weight and length than just their age. By following these guidelines, you ensure a safe, snug fit that supports healthy growth and comfortable sleep.
