SlumberSafe Sleep Sacks - the safe and comfortable way for all babies and children to sleep. SlumberSafe replaces blankets and duvets keeping your child at a comfortable temperature throughout the night. A sleeping bag can help your child settle when used as part of the bedtime routine. Wearable blankets are ideal when traveling, on holiday or sleepovers as children feel more at home in their sleep sack. Your child is naturally more unsettled when traveling. The familiarity of their wearable blanket will help them settle in new and unfamiliar surroundings. SlumberSafe sleep sacks come in six sizes from birth up to 10 years. Please refer to our size guide to help you choose the correct size for your child. You have a choice of four weights/tog.
