size guide

choosing the right size FOR YOUR CHILD

Slumbersafe baby and children sleep bags are available in six sizes, ranging from newborn babies right up to ten-year-old children!

When choosing a size, remember that your child should be able to kick and wriggle freely in the sleep bag. Ideally babies' feet should be at 3/4 of the sleep bag, leaving the bottom quarter of the sleep bag 'empty'.
