The layer suggestions in Little Layers are based on general guidance from the NHS and principles from the Lullaby Trust around safe temperatures for babies — both when out and about and at bedtime.

Every baby is different. Always check your baby's chest or the back of their neck to see if they feel too hot or cold, and adjust layers as needed. Hands and feet will often feel cool, which is normal.

Little Layers is a helpful guide, not a substitute for professional medical advice. If you're ever unsure about your baby's temperature or wellbeing, contact your GP or call 111.
