To all expectant parents, preparing clothes for your baby can be both exciting and overwhelming. Considering the frequent washing and rapid growth rate of newborns, it’s crucial to choose items that are practical and safe. This article guides you through the essential clothing items for newborns and key selection considerations for each.

1. Kimono-style Shirt

| Category | Explanation |
|---|---|
| Necessity | This is the most essential clothing item for newborns. Since babies have poor temperature regulation and their umbilical cord stump is still healing, the front-opening design is the most suitable, as it is easy to put on and take off without pulling over the head and keeps the belly covered. |
| Considerations | Material: Pure cotton (100% cotton) is fundamental for minimizing skin irritation. Knit fabrics (like jersey) with good sweat absorption and breathability are recommended. Size: Prepare a generous amount (5–7 pieces) of newborn size (50–60) as babies often spit up or soil their clothes frequently. |
| Other Notes | Seams: Choose designs where the seams are turned outwards or eliminated to prevent rubbing against the baby’s delicate skin. Usage Period: Typically used until about 1 month old (after the umbilical cord stump falls off). |
| Mandatory | Mandatory |
2. Newborn Underwear / Pajamas

| Category | Explanation |
|---|---|
| Necessity | Used as an indoor outfit after the kimono-style shirts or interchangeably with them. Separated tops and bottoms, or bodysuits (with snaps at the crotch), are practical as they are easier for diaper changes. They maintain the baby’s body temperature and absorb sweat indoors. |
| Considerations | Convenience: Choose designs with snaps at the shoulder or chest for easy dressing without irritating the baby’s head. Diaper Changes: Bodysuits or pants with snap closures at the bottom are convenient, eliminating the need to fully undress the baby. Season: Select appropriate thickness (thin cotton, thicker cotton) based on the season. |
| Other Notes | Size: Since babies grow quickly, it’s best not to purchase too many in advance. A slightly larger size that covers the hands and feet helps with temperature regulation. |
| Mandatory | Mandatory (After graduating from kimono shirts) |
3. All-in-One Suit / Romper

| Category | Explanation |
|---|---|
| Necessity | A one-piece outfit where the top and bottom are connected. It’s effective for temperature regulation because the baby’s belly is not exposed even with active movement. Useful for indoor wear or light outings. |
| Considerations | Ease of Change: Choose a design that opens with snaps or a zipper from the neck down to the ankle or along the legs for easy diaper changes. Zipper Safety: If using a zipper, ensure there is a fabric protector to prevent the zipper from touching the baby’s skin. |
| Other Notes | Activity: Both bodysuits (crotch closed) and rompers (shorts or long pants) fall into the all-in-one category. Their utility increases once the baby starts moving more actively, typically around 2–3 months old. |
| Mandatory | Recommended (Good for outings and temperature maintenance) |
4. Mittens / Booties

| Category | Explanation |
|---|---|
| Necessity | Mittens: Prevent the baby from scratching their face and causing injury, as newborn nails can be sharp and their arm movements are often uncontrolled (Moro reflex). |
| Booties: Stay on better than socks and help maintain the baby’s body temperature by keeping their feet warm. | |
| Considerations | Material: Choose non-fluorescent, pure cotton or other safe and soft materials, as the baby might put them in their mouth. Fit: Select a design that gently wraps around the wrist/ankle without being too tight or too loose, which could impede circulation. |
| Other Notes | Mitten Use: To aid brain and fine motor skill development, avoid prolonged use. Focus on frequent nail care and use mittens only when necessary (during sleep, after nail trimming, etc.). |
| Mandatory | Mandatory (Injury prevention and warmth) |
5. Newborn Cap

| Category | Explanation |
|---|---|
| Necessity | A newborn’s body heat is primarily released through the head. The cap is essential for preventing a sudden drop in body temperature indoors and outdoors, and it protects the head from the external environment during outings. |
| Considerations | Material: Select pure cotton with good breathability and sweat absorption, which is gentle on the scalp. Size: Choose a comfortable size that does not squeeze the head but can cover the ears. |
| Other Notes | Indoor Use: If the indoor temperature is adequate, excessive cap wearing can worsen heat rash (Taeyeol). It should mainly be used during outings or immediately after bathing when temperatures fluctuate. |
| Mandatory | Mandatory (For temperature regulation) |
6. Socks

| Category | Explanation |
|---|---|
| Necessity | Newborns often have cold hands and feet due to less active blood circulation. Socks help maintain foot warmth, contributing to overall body temperature stability. They also protect the feet during outings instead of shoes. |
| Considerations | Material and Tightness: Choose soft socks with gentle elastic bands that do not constrict the ankle, ensuring they do not impede circulation. Anti-slip: For babies learning to walk, socks with anti-slip grips are useful. |
| Other Notes | Bootie Alternative: Socks can be used indoors instead of booties. Since socks slip off easily, using one-piece outfits that cover the feet is a good alternative. |
| Mandatory | Mandatory (For warmth) |
7. Bib

| Category | Explanation |
|---|---|
| Necessity | Newborns frequently spit up or drool, so their clothes quickly become soiled and damp. Bibs prevent clothes from contamination, thus reducing frequent washing and protecting the baby’s skin from drool-induced dampness. |
| Considerations | Absorbency and Waterproofing: Products with a cotton front (good for absorbing drool) and a waterproof back to prevent soaking the clothes are practical. Closure: Snaps or soft Velcro are convenient and safe, ensuring they don’t restrict the baby’s neck. |
| Other Notes | Plenty of Stock: Since they are used multiple times daily, prepare a generous amount (5–7 pieces or more) for frequent rotation and washing to maintain hygiene. |
| Mandatory | Mandatory (For hygiene and reducing laundry) |
Since baby clothes directly touch the skin, it is best to wash them with non-fluorescent detergent and dry them thoroughly in sunlight before the baby arrives. 😊
