【ENG】Stay on top for all seasons! Choosing undershirts for your baby

Undershirt helps maintain the baby’s body temperature constant, preventing the baby from getting too cold or too hot. So, choosing an undershirt that will help your baby regulate their body temperature is necessary.

A baby’s skin is thinner and more sensitive to external stimuli than an adult’s skin, so it is necessary to protect a baby’s delicate skin. You can help prevent your baby’s skin issues by choosing an undershirt made of gentle-to-skin materials.

Babies who wear a comfortable undershirt have fewer skin issues and may comfortably adapt to warm and cold seasons throughout the year. A comfortable undershirt also allows babies to sleep comfortably, which is critical to their development.

What is the best undershirt for newborns?

Since newborns cannot yet regulate their body temperature, undershirt helps them. undershirt for the newborn period should protect the baby’s delicate skin while allowing the baby to move more easily. It should also be easy to wear.

Here, we will introduce you to the characteristics of each type of undershirt or onesie. Rest assured, preparing the following four types of undershirt will help you choose the right clothes for your baby throughout the year.

• Short onesie

It is a spring and summer staple. Its length reaches the waist, making it easy to layer. Its ability to absorb sweat makes it perfect for hot days. A short onesie is often layered at the front with ties, similar to a kimono, and it is also convenient for diaper changes.

• Long onesie

This item is ideal for boosting warmth during winter. It is perfect for babies in the sleeping phase since it covers the legs and is suitable for winter or air-conditioned environments. It can be layered over a short onesie. The open hem makes it especially helpful during the newborn stage when leg movement is minimal and diaper changes are frequent.

• Combination onesie (combinations)

This type features a short onesie for the upper body and long pants for the lower body. The design includes snap buttons in the crotch to divide the legs, making diaper changes simple. It will come in handy when your baby becomes more active.

• Rompers

Key Points for choosing undershirt for each season

Knowing the best fabrics, designs, and ways to dress your baby for each season will not only keep your baby comfortable all year round but will also reduce skin problems and temperature regulation challenges. We hope this guide will help you choose the right undershirt for your baby for each season.




What to choose from materials? Organic cotton and silk

• Organic cotton: Grown without pesticides or chemical fertilizers, making it a safe material for babies. It is highly breathable and moisture-absorbing, making it ideal for babies who sweat frequently.
• Silk: Made of natural protein, silk feels pleasant on the skin. It also has exceptional moisture retention properties, so it will be warm and comfortable during winter and breathable and cool during summer. Thus, it’s a versatile textile that can be used all year.

For spring and summer: Breathability and water absorbency are the keys!

Spring and summer have high temperatures, and babies tend to sweat easily. If your baby wears a sweaty undershirt for a long time, the skin will get steamy, which can cause skin problems such as prickly heat and heat rash. This is where breathability and water absorbency are important.

• Breathability: Temperatures rise during the spring and summer, causing babies to sweat and overheat. The fabric’s ability to let air pass through allows moisture to escape from the skin. This prevents overheating while keeping the baby’s skin dry and comfortable. It also helps prevent heat rash and skin problems.
• Absorbency: Choose an undershirt that can effectively absorb your baby’s sweat. Materials with low absorbency tend to leave sweat on the skin, leading to irritation and discomfort. Choosing fabrics that quickly absorb sweat can keep the skin dry and clean.

Autumn and winter: How many layers of undershirt my baby need?

The temperature drops significantly from autumn to winter, making babies more susceptible to the cold. Effective cold weather preparations are important for newborns, as they can not properly regulate their body temperature.

Many parents are concerned about how many layers of undergarments to put on. It is advisable to layer 1-2 pieces of undershirt with one piece of baby wear. When outside the room, layer a vest, socks, hat, and blanket to keep the baby warm. However, since babies sweat easily, do not overdress them.

Unlike spring and summer, Autumn and winter are seasons when heating is commonly used. You don’t need to prepare an excessive piece of undershirt since the washed undershirt will dry quickly under the heater. For example, if you prepare 4-5 pieces of short and 4 pieces of long undershirts or combination onesies, your little one will be ready to spend the autumn and winter comfortably.

Adjust your baby’s body temperature by layering undershirts!

Undershirt is an essential item for regulating your baby’s body temperature. Dressing your baby in layers will help them adapt to changes in room temperature and keep them comfortable.

Layering techniques by season

Spring

In the spring, there is a temperature difference in the weather and from the cold of winter, so layer undershirts and long-sleeved babywear to adjust to the room temperature. Here are examples of how to layer a baby undershirt:

• Short onesie + long onesie
• Short onesie + combinations or rompers
• Combinations + rompers

When going outside, layer the clothes with a thin jacket, vest, hat, or other accessories to help maintain your baby’s body temperature. If your baby is sweating, it is a sign that your little one is too hot. In that case, remove one layer of undershirt to adjust the temperature. When the temperature rises, your baby can stay indoors with just one piece of a combination onesie.





Summer

Summer temperatures can rise to 30°C and can be highly humid. Babies have higher body temperatures and sweat more easily than adults, so choose an undershirt made of cotton and silk. These fabrics have excellent breathability and moisture absorption properties and also dry easily. The following undershirt and baby clothes are recommended.

• Short onesie + combinations
• Short onesie + long onesie
• Short onesie + rompers

Babies spend most of the summer indoors in air-conditioned rooms. To prevent them from getting too cold, layer one short underclothes and one thin combinations or rompers. During hot weather, it is important to change the undershirt frequently. Furthermore, if the towel on the head or back is damp, put a sweat pad in the back and replace the towel.




Autumn

In autumn, the temperature difference can reach 10°C again, just like in spring. However, the summer heat remains, so clothing should be summer-appropriate. You can also help your baby maintain body temperature by switching to a long-sleeved undershirt.

• Short onesie + long onesie
• Short onesie + combinations or rompers
• Short onesie + long onesie + rompers

Layer two undershirts for a baby who will spend time in a room with a temperature of 23°C. Layering with a romper or long-sleeved undershirt will suffice when the temperature slightly drops. However, if you overdress your baby, it will be difficult for the baby to move, so either reduce the number of undershirt layers or choose lightweight baby wear. Use a vest or blanket to keep your baby warm from the cold outdoor temperature.




Winter

In winter, preparing some clothes against the cold is especially important. We will introduce how many layers of undershirts and clothes your baby should wear to protect them from the cold, as their body temperature control is still developing.

• Short onesie + long onesie
• Short onesie + long onesie + combinations
• Short onesie + long onesie + rompers

If your baby spends most of their time indoors in a heated room temperature of 25°C, be careful not to overdress them or put them in thick clothes. This can lead the baby to sweat excessively, which can cool the body, so reduce one layer of the undershirt. Even if your baby is not wearing socks, one or two layers of undershirt and one piece of lightweight clothing will be enough. When going out, you can protect your baby from the low temperatures of winter by using a hat, vest, and swaddling cloth.




Adapting to the temperature difference between indoors and outdoors

• When outside: Since outdoor temperatures are often lower than indoors, layer baby clothes and accessories on top of the undershirt to prevent sudden drops in body temperature.
• Pay attention to changes in body temperature: Babies’ body temperature regulation is less developed than that of adults. Therefore, it is important to check body temperature frequently and adjust the number of undershirt layers accordingly.
