FAQs about Organic Cotton Sacks

  • What is a baby sleep bag or sack?

    A baby sleep bag, also called a wearable blanket or sleep sack, is a bag-like garment or covering worn by infants for sleeping. It replacing loose blankets in the crib that can cover your baby's face and interfere with breathing.  

    Since 2005, The American Academy of Pediatrics has recommended the use of wearable blankets for safe sleep. Unlike regular blankets, a wearable blanket or sleep sack is worn over your child's sleepwear, so it won't be kicked off and baby stays covered all night. The sleep sack will become part of your child's bedtime routine, providing a sense of security and comfort.

  • Are your organic cotton sleep bags winter or summer weight?


    Our organic cotton baby sleeping bags are made of one layer 100% organic cotton fabric in interlock knit. They are summer weight.

  • Do I need more than one Woolino sleeping bag?

  • What should my baby wear when sleeping in a Woolino Organic Cotton Sleep Bag?

    We recommend natural breathable fabrics like cotton or merino wool. Dress your baby depending on the their room temperature. Do not let your child overheat. Woolino pajamas or bodysuits are ideal for layering or to wear inside a Woolino sleep bag. The temperature in most rooms will rise and fall throughout the night, and the merino fiber has the remarkable ability to regulate body temperature.

  • How do I know if my child is hot or cold?

    Please check if your baby is hot or cold while sleeping by touching her tummy or behind her neck. Touching baby’s hands and feet are NOT good indications of their actual body temperature.

  • Why don’t the sleeping bags have sleeves? Won’t my child get cold?

    Our baby sleeping bags are sleeveless to ensure air circulation around baby’s chest. Babies that sleep with traditional sheets and blankets rarely sleep with their arms underneath the blankets. We recommend layering under-garments to ensure your child is perfectly comfortable in their sleeping environment. It is normal for babies to have cold hands and feet due to their still-developing circulation systems and it is not an indication that they are cold. Checking behind baby’s neck or his/her tummy will give you better indication of baby’s body temperature.
