Safe Sleep & Usage Notes

Your baby’s safety matters deeply to us. This sleeping bag is designed to support safer sleep when used correctly, following widely recommended safe-sleep practices in Australia.

• Place baby on their back on a firm, flat cot or bassinet mattress.
• Remove all loose bedding, pillows, toys, blankets, bumpers or soft items from the sleep space.
• Do not add extra blankets on top of the sleeping bag — dress baby in suitable layers underneath depending on room temperature.
• Ensure the sleeping bag size is appropriate — too large can pose a hazard.
• Do not use in strollers, car seats, swings, inclined surfaces or non-flat sleep environments. For safe sleep, always use a cot/bassinet with a firm, flat mattress.
