To all expectant parents, here is a list of Developmental Gear (Mobility and Play Items) that aids your baby’s growth and development while enhancing parent convenience. Since these items directly relate to your baby’s safety and proper posture, always prioritize safety certification and age-appropriateness during selection.

1. Stroller

| Category | Explanation |
|---|---|
| 1) Necessity | An essential item for safe and comfortable mobility when taking the baby outside for activities or walks. It helps reduce parental fatigue and allows the baby to receive developmental stimulation and adapt to the external environment. |
| 2) Considerations | Safety: Verify official safety certifications such as KC certification and ensure the safety harness is sturdy. Newborn Seating: Since newborns have underdeveloped spines, select a model with a seat that reclines 170^\circ or more (pram style) or one that allows for the attachment of a newborn infant insert. Portability: Consider your family’s lifestyle (car trunk size, use of stairs) and check the weight and ease of folding. |
| 3) Other Notes | First Ride: Usable from the moment of hospital discharge, but generally recommended for short outings after the first month of life. |
| Mandatory | Mandatory (For outings) |
2. Car Seat

| Category | Explanation |
|---|---|
| 1) Necessity | The most important essential item for protecting the baby’s life and safety during car travel. It minimizes physical injury to the baby in the event of a traffic accident. Car seat installation is mandatory for infants and toddlers by law in South Korea. |
| 2) Considerations | Safety Standards: Check crash test results and safety certifications (KC, European ECE, etc.). Rear-Facing: Must be used in the rear-facing position from newborn to at least around the first birthday (13 kg) to protect the neck and spine. Installation: ISOFIX systems are safer and easier to install. |
| 3) Other Notes | Required Time: Needed from the moment of hospital discharge. Must be installed in the car before the baby’s birth. |
| Mandatory | Mandatory (For car-owning households) |
3. Infant Car Seat / Carrier

| Category | Explanation |
|---|---|
| 1) Necessity | A newborn-specific car seat, typically used up to 13 kg. It’s convenient because the baby can be carried like a basket after detaching it from the car, or it can be attached to a stroller frame (travel system). |
| 2) Considerations | Safety: Check safety standards, just like with a standard car seat. Convenience: Choose a lightweight model that is easy to carry and includes a newborn insert to stably support the infant’s posture. |
| 3) Other Notes | Usage Period: Due to the short usage period, many opt to buy second-hand or rent. It can help the newborn adapt to the car seat environment from an early stage. |
| Mandatory | Recommended (Newborn safety and travel convenience) |
4. Baby Carrier

| Category | Explanation |
|---|---|
| 1) Necessity | Allows parents to use both hands freely for daily activities while holding the baby. It provides comfort to the baby, aiding emotional development, and enhances the parent-baby bond. |
| 2) Considerations | M-Position: To prevent developmental dysplasia of the hip (DDH), choose a product that supports the baby’s bottom broadly, allowing the legs to be spread in an ‘M-shape’ position. Newborn Insert: Since newborns cannot hold up their head, use a model with a secure newborn pad or definite head support. |
| 3) Other Notes | Usage: Before use, always familiarize yourself with the correct wearing method. Ensure the baby’s spine is not slumped by firmly supporting the lower back and hips. |
| Mandatory | Mandatory (Parenting essential) |
5. Hip Seat Carrier

| Category | Explanation |
|---|---|
| 1) Necessity | Features a wide platform (hip seat) worn around the waist to distribute the baby’s weight, reducing the strain on the parent’s shoulders and back while carrying the baby. Primarily used after the baby can sit up independently (around 6 months). |
| 2) Considerations | Stability: Ensure the hip seat part is non-slip and firmly secured. Baby’s Posture: Check that the baby’s legs are not overly splayed and that the baby is comfortable. |
| 3) Other Notes | No Newborn Use: Absolutely must not be used for newborns. It can strain the newborn’s spine and lower back, being detrimental to hip development. |
| Mandatory | Optional (After baby starts sitting up) |
6. Carrier Warmer

| Category | Explanation |
|---|---|
| 1) Necessity | An outerwear-like cover used in cold weather when carrying the baby in a carrier or sling, maintaining the baby’s body temperature and blocking cold wind. |
| 2) Considerations | Warmth: Check for windproof/waterproof features and sufficient thermal insulation to block the cold. Convenience: Ensure it is easy for both parent and baby to attach and detach, and that the head section is adjustable so as not to obstruct the baby’s face. |
| 3) Other Notes | Temperature Control: Excessive warmth in a warm indoor environment can cause the baby to sweat, so adjust according to indoor/outdoor temperatures. |
| Mandatory | Optional (Recommended for autumn/winter outings) |
7. High Chair

| Category | Explanation |
|---|---|
| 1) Necessity | Helps the baby eat safely and in a proper posture, starting around the time of solid food introduction (around 6 months). Provides a separate eating space, aiding in the formation of regular eating habits. |

| Mandatory | Mandatory (After starting solids) |
8. Bouncer

| Category | Explanation |
|---|---|
| 1) Necessity | An auxiliary item that allows the baby to be safely laid or seated temporarily, protecting the parent’s wrists and back. The vibration or gentle rocking function aids in the baby’s emotional stabilization, allowing the parent a brief rest or time for other tasks. |
| 2) Considerations | Safety: Ensure the structure is stable so it won’t tip over and comfortably supports the baby’s back and neck. Function: Choose between manual or automatic models (vibration, sound) based on parental needs. Newborn Support: Check for a newborn insert to stably support the newborn’s head. |
| 3) Other Notes | Avoid Prolonged Use: Avoid leaving the baby in the bouncer for too long. This may hinder the baby’s spinal development and reduce their activity level. |

10. Mobile (Black & White / Color)

| Category | Explanation |
|---|---|
| 1) Necessity | A toy that aids the baby’s visual development and provides emotional comfort, reducing boredom while lying down. |
| 2) Considerations | Black & White Mobile: Newborns (0–2 months) have poor vision and can only perceive high-contrast black and white. Color Mobile: Switch to color when color recognition develops (after 3 months). Safety: Must be firmly secured in a safe location out of the baby’s reach. |
| 3) Other Notes | Installation Position: Install so the baby looks at it at a 45^\circ angle to the side, not directly in front, and alternate sides to encourage visual tracking development. |
| Mandatory | Recommended (Visual development and play) |
