What Should Baby Wear to Sleep at 27°C+?
Quick answer
In a 27°C+ room, keep sleepwear ultra-light — a short-sleeve bodysuit under a 0.2 TOG sack, or bodysuit alone if the room stays that warm.
- ultra-light sleep sack (about 0.2 TOG)
- short-sleeve cotton bodysuit under an ultra-light sleep sack (or bodysuit only)
- No hats indoors for sleep
- No loose blankets in the crib
Sleepwear for a 27°C+ nursery
Room temperature bands matter more than exact degrees. Within 27°C+, the TOG family usually stays the same — then the chest check fine-tunes.
In a 27°C+ room, keep sleepwear ultra-light — a short-sleeve bodysuit under a 0.2 TOG sack, or bodysuit alone if the room stays that warm.
Look for a sleep sack labeled around 0.2 TOG. Brands vary; cross-check their chart, then trust the chest.
Confirm with the chest check
About 10–15 minutes after settling (or outside), feel the chest or back of the neck: warm and dry is right; sweaty means remove a layer; cool means add one. Cool hands and feet alone are normal.
Safe-sleep reminders
No loose blankets, pillows, or soft objects in the sleep space for the first year (AAP).
No hats indoors during sleep. Stop swaddling at the first signs of rolling.
This is general dressing guidance, not medical advice. Every baby is different — for fever, premature birth, or any medical concern, follow your clinician.
Frequently asked questions
What TOG for 27°C+?
Around 0.2 TOG (ultra-light) is the usual starting point, with short-sleeve cotton bodysuit under an ultra-light sleep sack (or bodysuit only). Confirm after settling.
Should baby wear socks to bed?
Usually not if the sleepsuit or sack covers the feet. Judge warmth by the chest, not the toes.
