What Should My Baby Wear to Sleep in Air-Con? (24°C to 26°C Guide)

In Singapore, a nursery may feel warm and humid before bedtime and noticeably cooler once the air-conditioner has been running. There is no single outfit that is right for every baby at 24°C–26°C: airflow, humidity, the garment, your baby’s health and how warm they naturally run all matter. Use the room temperature as a starting point, then check your baby and adjust.

Start with safe-sleep basics

Singapore’s HealthHub safe-sleep guidance recommends placing a baby on their back on a firm, flat sleep surface and keeping pillows, loose blankets, bumper pads, toys and other soft objects out of the sleep area. The American Academy of Pediatrics’ parent guidance gives similar advice and suggests wearable sleep clothing as an alternative to loose bedding.

What to try at 24°C–26°C

A practical first step is one fitted, lightweight sleep layer, such as a long-sleeve sleep suit. If you use a sleep sack or swaddle product, follow its size, fit and use instructions and account for the clothing underneath. Do not add a loose blanket to compensate for cool air.

• Start simple: choose one well-fitting layer and observe your baby rather than dressing only by the thermostat.
• Check the torso: feel the chest or upper back. If the skin is hot, sweaty or flushed, remove a layer or adjust the room. Hands and feet can feel cooler than the torso.
• Keep air indirect: avoid positioning the cot where an air-conditioning vent blows directly onto the baby.
• Recheck after changes: air-conditioning cycles and overnight temperatures can change how the room feels.

Ask your child’s healthcare professional for individual advice if your baby was premature, is unwell, has a fever or has another condition affecting temperature regulation.

Sleepwear options

A zip sleep suit provides arm and leg coverage in one fitted garment. Hae Hae’s main fabric is 95% bamboo and 5% spandex, and its products are sewn by the company’s own team at its owned Batam facility.

For parents who use wearable sleep products, compare the current sizes and instructions for the HaeZip™ sleep sack and swaddle. Stop swaddling when your baby shows signs of attempting to roll, and follow current medical guidance and the product instructions.

Older children can compare long- and short-sleeve kids’ pyjamas according to the room and their individual comfort.
