When reading the resources fir safe sleeping I note the reference to not using lambswool. Would you please confirm if this is sheep’s skin products or also any blankets made from pure wool as I understood this was a breathable material like cotton? Thanks for your advice

Sheepskins & lambswool are not recommended for use in baby’s sleep environment.
Red Nose recommends that a baby’s sleep surface is firm. Sheepskins can create a soft surface for baby to sleep on, can contribute to an increase the risk of overheating or may become loose covering baby’s head & face.

Red Nose recommends using only those blankets are lightweight.
If blankets are being used instead of a safe sleeping bag, it is recommended to place your baby with his or her feet at the bottom of the cot, using layers of lightweight blankets that can be added or removed easily according to the ambient feel of the room. Tuck blankets in firmly so they cannot become loose and cover your baby’s head and face during sleep.

Ensure there is no soft bedding in baby’s sleep environment. Soft bedding (pillows, doonas, loose bedding or fabric, lambswool, bumpers or soft toys) in the cot is unnecessary and may cover baby’s face and obstruct baby’s breathing.

Never put soft bedding under the bottom sheet, such as a sheepskin, as this makes the sleeping surface too soft.
