A wearable blanket that helps baby sleep (and stay asleep), so you’re not up all night. Our baby sleeping bags are designed to be safe sleeping, easy nappy changes, temperature-regulating, TOG rated and so soft you’ll have to touch it to believe it. Voted the No. 1 Sleep Bag by The Bump in 2019, our bamboo sleeping bags are award winning, buttery soft and keeps the baby at a comfortable temperature all night long. Available in 1 TOG for summer sleeping and 2.5 TOG for winter sleeping and two sizes to suit a wide range of babies. TOG rating is a system that measures warmth and calculates how quickly a fabric uses heat. It is the standard when choosing the appropriate sleeping bag for your baby, depending on the ambient temperature in your nursery. We recommend a heavier TOG during cooler months and a lighter one during warmer months.
