“When I first cared for my newborn, I often wondered, “Is my baby warm enough? Or maybe too hot?” I soon realized that babies are sensitive to both cold and heat — and this doesn’t change as they grow.”
The reason babies are sensitive to temperature is related to their physical development. Newborns have less body fat and a relatively larger surface area, which makes them lose heat quickly and get cold easily. At the same time, their sweat glands are not fully developed, so when they become too warm, they can sweat but cannot cool down effectively. Unlike adults, babies cannot regulate their body temperature efficiently. That’s why dressing them requires a careful balance of warmth and breathability.
When my baby was still a newborn, layering was the key to keeping him comfortable year-round. Instead of heavy clothing, I focused on breathable fabrics and soft base layers. I loved using kimono clothes as the first layer. The kimono-style design avoided pulling clothing over the head, making dressing gentler and easier. The muslin fabric was soft, lightweight, and breathable, so even when I added another layer, it never felt stuffy.

Sleep is always a concern for moms. In the early months, using a Swaddle helped keep my baby warm while mimicking the snug feeling of the womb. It reduced the startle reflex and encouraged better sleep.
At the same time, I also paid close attention to my baby’s belly. A baby’s belly is especially sensitive to temperature changes, and even slight exposure can lead to discomfort or gas. During those early months, I often used a Belly Band — a soft baby tummy wrap — to keep the belly covered and maintain stable warmth, especially during sleep. It gave me peace of mind knowing that in those early newborn days, my baby’s delicate belly stayed softly covered and comfortably warm.

As my baby grew and started rolling over, swaddling was no longer safe. That was when I transitioned to a sleep sack. A sleep sack is essentially a wearable blanket designed for babies. It keeps older babies warm at night without loose bedding, and because it can’t be kicked off, it helps prevent your baby from getting cold during the night.

I also felt more at ease knowing that it wouldn’t cover my baby’s face, reducing the risk of suffocation and supporting safer sleep. Most sleep sacks are designed with side openings or zippers, making diaper changes or nighttime feeds easier without fully waking the baby. It’s a safer and more practical solution for babies who are becoming more active but still need consistent warmth and comfort during sleep.
For bigger babies and toddlers, I continue to follow the layering method — often called the “onion style” of dressing. I usually start with a thermal inner layer, then everyday clothing, add a vest for extra warmth, and finish with a jacket when going outdoors. This way, I can easily remove layers if the temperature changes, preventing overheating while still protecting them from the cold.
Now I understand that keeping a baby comfortable isn’t about piling on layers. Babies fear both the cold and the heat. The key is observing them, choosing breathable fabrics, layering thoughtfully, and adjusting as they grow. Checking the back of the neck remains the most reliable way to know if your baby is comfortable — warm and dry means just right.
Motherhood has taught me that warmth is about balance. With the right clothing and gentle attention, we can keep our babies comfortable in every season and at every stage.
