Bedtime clothing

What temperature should baby’s room be?

Between 18 and 20 °C (65 to 68 °F), as health authorities recommend. If the room is warmer, use lighter clothes; if it is cooler, add a layer of clothing, never a duvet or blanket.

What should baby wear to sleep at 19 °C (66 °F)?

From 18 to 19 °C (65 to 67 °F): a long-sleeve bodysuit, pyjamas and a padded sleep sack. Then feel the back of baby’s neck: warm and dry is fine.

What does TOG mean on a sleep sack?

TOG rates how warm a fabric is: the higher the number, the warmer the sleep sack. Makers usually quote 0.5 to 1 TOG for a light sleep sack and about 2.5 TOG for a padded one. Values vary between brands, so follow your own sleep sack maker’s chart.

The temperature falls between two ranges: what now?

Each range starts at the temperature shown: 21.5 °C gives the 20-21 °C outfit. If in doubt, feel baby’s neck or chest: clammy or sweaty means remove a layer.

Does baby need a hat or a blanket?

No. Indoors, babies do not need a hat: they lose heat through their head. The sleep sack replaces duvets and blankets, which can cover baby’s face.

How do I know if baby is too hot or too cold?

Feel the back of the neck or the chest: warm and dry is fine; clammy means too hot. Cool hands or feet are normal. For guidance only, not medical advice: if baby has a fever or you are unsure, ask your doctor.
