Baby Sleeping Bags

Baby sleeping bags are a safe and convenient alternative to loose blankets in the cot, designed to keep your baby at a comfortable temperature all night long. They come in a range of TOG ratings to suit different seasons and room temperatures. Browse our collection of baby sleeping bags for newborns through to toddlers.

TOG stands for Thermal Overall Grade and measures the warmth of a sleeping bag. A lower TOG (0.5 to 1.0) is suitable for warmer months or heated rooms, while a higher TOG (2.5 to 3.5) is better for cooler nights. Most manufacturers provide a temperature guide to help you choose the right TOG for your room temperature.

Yes, baby sleeping bags are considered safer than loose blankets as they cannot cover your baby's face during sleep. They are recommended by safe sleep guidelines as part of a safe sleep environment. Always ensure the sleeping bag fits your baby correctly with a snug neck opening so they cannot slip inside.

Baby sleeping bags are generally sized by age and weight rather than height. It is important to choose a size where the neck opening fits snugly and your baby cannot slip down inside the bag. Most brands offer sizes for newborns, 6 to 18 months, and 18 to 36 months.

Many sleeping bags are available in newborn sizes suitable from around 3 kg. However, very young babies may benefit from swaddling before transitioning to a sleeping bag. If you are unsure, speak with your maternal health nurse or paediatrician about the best sleep option for your newborn.

What your baby wears underneath their sleeping bag depends on the TOG rating and the room temperature. A general guide is to dress your baby in a nappy and singlet under a 2.5 TOG bag, or add a long-sleeve onesie in cooler conditions. Avoid over-dressing your baby as overheating is a risk factor for SIDS.
