What Should Baby Wear to Sleep in Singapore?
After months of planning the perfect nursery, birth plan and discharge outfit, many first-time parents get home and face a new question: how do you dress your newborn for sleep? In Singapore's heat and humidity, with the aircon on or just a fan, it's easy to get it wrong. This guide covers what to dress your baby in by room temperature, how to tell if they're comfortable, and safe-sleep basics.
Quick answer: In an air-conditioned room at 23–25°C, a long-sleeve sleepsuit is usually enough. In a warmer room or with only a fan, a short-sleeve onesie works better. Skip hats and loose blankets. To check if your baby is comfortable, feel their chest or the back of their neck: it should feel warm and dry. If it's sweaty or hot, remove a layer. If it's cool, add one more layer.
What to dress baby in, by room temperature
Room temperature | What to dress baby in |
Above 26°C (fan only) | Short-sleeve onesie |
25–26°C | Short-sleeve onesie, or a sleepsuit with mittens and footies folded back |
23–25°C | Long-sleeve sleepsuit, or a short-sleeve onesie with a light bamboo swaddle (for newborns who are not rolling yet) |
This is a general guide. Every baby is different, so check how they feel and adjust.
1. Keep the room at a comfortable temperature
For many Singapore families, aircon is a must at bedtime, and it's safe for babies when set at a moderate temperature. A room between 23°C and 25°C is a comfortable range for most babies.
Point the aircon or fan away from your baby so the airflow doesn't blow directly on them.
No aircon? Keep the room ventilated with a fan and dress your baby lightly, in a short-sleeve onesie.
2. Choose breathable fabrics
Natural, breathable fabrics help your baby stay at a comfortable temperature through the night. Bamboo is a good choice for sleepwear due to its exceptional softness, breathability, and temperature-regulating properties. It keeps babies comfortable by allowing air circulation, reducing the risk of overheating and skin irritations. Bamboo fabric is hypoallergenic, gentle on delicate skin, and offers natural UV protection. Its durability ensures longer milage for parents (and saving money) and the best part is... it gets softer with every wash!
3. Keep it simple
Avoid sleepwear with too many snaps, buttons, or complicated fastenings. When your newborn wakes for night feeds or diaper changes, you'll want to get them changed and back to sleep with as little fuss as possible.
The Green Edit's EasyZip sleepsuits feature two-way zippers for easy dressing, undressing and diaper changes in the middle of the night.
4. Mittens and footies: when to use them
A baby's hands and feet often feel cooler than the rest of their body. This is normal, so check their chest or the back of their neck to judge whether they're warm enough.
There are two good reasons to cover hands and feet at night: the room is on the cool side, or your baby scratches their face or skin in their sleep. Newborns' nails are sharp and grow quickly, and scratching can irritate sensitive or eczema-prone skin.
The Green Edit's baby sleepsuits have foldover mittens and footies, so you can cover hands and feet when needed and open them up for play during the day. There's no need for separate mittens or socks that fall off in the night.
5. Layer clothing instead of using blankets
Avoid loose blankets, pillows and soft toys in your baby's cot for the first 12 months. Instead, adjust how warm your baby is by layering their clothes:
Warmer room: a comfortable short sleeved onesie or bodysuit
Cooler room: a soft long-sleeve sleepsuit with optional bamboo swaddle to help them feel safe. TGE's Tip: When swaddling, leave room for the hips and legs to bend and move. Stop swaddling once baby shows signs of rolling.
6. Change the diaper before bedtime
This is so important but often overlooked. Opting for high-quality diapers (such as Rascal + Friends, Offspring, nino nana, Merries’ First Premium, Huggies Platinum Naturemade) is also crucial for promoting better newborn sleep.
High-quality diapers provide comfort with a soft fit, keep the baby's skin dry, and prevent discomfort from prolonged wetness. High-quality diapers with excellent absorption and leak protection contribute to longer periods of uninterrupted sleep. They are designed with breathable materials to regulate body temperature and promote airflow, preventing overheating. High-quality diapers are often hypoallergenic, minimizing the risk of skin irritations and allergies. With their superior absorption and leak prevention, good diapers reduce the need for nighttime changes, allowing newborns to stay in a deep sleep state for longer periods.
Safe sleep reminders
Always place your baby on their back to sleep.
Use a firm, flat mattress with a fitted sheet.
Keep the cot clear of pillows, blankets, bumpers and soft toys.
Remove hats during sleep.
Stop swaddling once your baby starts showing signs of rolling.
By implementing these tips, you can create a comfortable and safe sleep environment for your newborn, allowing them to rest peacefully and helping both baby and parents enjoy better quality sleep throughout the night.
