FAQs About Newborn Sleep Bags

What TOG rating do I need for a newborn sleep bag?

The right TOG depends on your little one's room temperature. For warmer nights above 24°C, choose a lightweight 0.5 TOG. A 1.0 TOG is great for rooms between 20–24°C, 2.5 TOG for cooler rooms between 16–20°C, and 3.5 TOG for those extra-chilly nights below 16°C.

Are newborn sleep bags safe?

Yes, when they're the right size and used as directed, sleep bags are a cozy alternative to loose blankets. Look for a secure fit around your baby's neck and armholes, and choose the right TOG for their room temperature. Our sleep bags are thoughtfully designed to help keep little ones comfortable through the night.

What size sleep bag does a newborn need?

The best sleep bag is one that fits your little one comfortably and securely. It should fit well around the neck and armholes without being too tight, with plenty of room for little legs to move. Check the size guide on each product page to find the best fit based on your baby's height and weight.

What material is best for a newborn sleep bag?

Soft, breathable fabrics like bamboo and organic cotton are lovely choices for delicate newborn skin. They're gentle and breathable, while bamboo also helps wick away moisture to keep your little one comfortable throughout the night.

How long do babies wear sleep bags?

Sleep bags can grow with your little one from those early newborn nights well into toddlerhood. As your baby grows and becomes more active, you can move from swaddling to a sleep bag and eventually to a footed sleep bag that gives busy little feet more freedom to move.
