About the inbetweenie™

The new inbetweenie™ by Girl + Boy is a range of fully enclosed, lightweight 100% cotton sleep sacks or sleeping bags for babies who don't like being swaddled or those who have begun to roll.

Based on the simple concept of a safe, soft boundary, the inbetweenie™ helps babies to sleep peacefully without the constraints or risks of a traditional swaddle or danger of loose blankets.

The inbetweenie™ range comes in two weights: the Extra Light, which is TOG rated at 0.2 and ideal for hot summer nights over 25°C, and the Original Muslin which can be used for most of the year simply by adding or removing layers of your baby's clothing. The Original is ideal for sleeping environments between 18-25°C degrees, including rooms which are cooled by air conditioning or fans, right through to warmer winter nurseries. Please refer to our Nursery Temperatures & Clothing Guidelines for more information. 

The unique design of the inbetweenie™ helps to control the startle or moro reflex while still allowing your baby to find their fist and self soothe. It offers enough room to naturally stretch out their hips and safely expand their chest, while allowing enough movement to safely roll on to their front and back again.

The full enclosure sleep sack and soft neckline keeps little hands and necks covered as well as protected from mosquitoes or bugs, so your baby will stay cosy through the night.

When your baby begins to roll, usually at around 3 months old, it is time to transition or wean them from sleeping in a swaddle. The inbetweenie™ provides an alternative way to teach your baby to sleep unswaddled without needing to expose her arms or ever go 'cold turkey'.

Sleep regression, where a baby suddenly begins waking up at night for no apparent reason, is a frustrating time for parents. As babies develop, their mobility increases and their idea of comfort also changes, so we believe that switching to a new style of bedding, such as the inbetweenie™, can be a positive step to helping your child sleep through the night again. 

The inbetweenie™ Original Muslin is crafted from a double weight 100% muslin cotton while the Extra Light is made from a feather fine cotton voile. Both fabrics are natural and breathable with antibacterial fibre, preventing the risk of overheating. This natural construction makes the inbetweenie™ range suitable for eczema and dermatitis sufferers, prohibiting scratching, and can also be worn directly against your baby's sensitive skin.

The inbetweenie™ provides all the benefits of sleeping with a sheet or wrap but with the safety of a baby sleeping bag. You can enjoy peace of mind knowing your baby is kept comfortable throughout the night as well as safe.
