Does Red Nose endorse the Snuggle Hunny product? This is an item shaped like a cloth bag designed to sleep babies in after they have been wrapped. Used for newborns to help stop their arms coming out of the wrap.

Some babies do not respond well to wrapping as they like to touch their face or suck their fingers.
Some babies roll very early & it is preferable they are not wrapped.
Red Nose has the following information about wrapping/swaddling.
Use only lightweight wraps such as cotton or muslin (bunny rugs and blankets are not safe alternatives as they may cause overheating).

For wrapping to be effective, the wrap needs to be firm but not too tight. Techniques that use tight wrapping with legs straight and together increase the risk of abnormal hip development, while loose wraps are also hazardous as they can cover baby’s head and face.

Ensure that baby is not over dressed under the wrap. Use only nappy and singlet in warmer weather and dress baby in a lightweight grow suit in cooler weather.
