單肩式揹帶採用斜跨式設計，多數由棉或混合纖維物料製成，主要包括布包(wraparound)、環扣(ring)和袋式(pouch)三種類型。較小嬰兒可以採用前揹搖籃式或前揹直立式；較大嬰兒則可以用前側揹式。這類揹帶輕巧便攜， 售價較平，但沒有卸力設計，長時間使用可能會令肩膊和腰部疲勞，且限制了嬰兒腿部活動。

雙肩式揹帶利用肩帶和腰帶將受力平均分佈，包括傳統揹帶、軟結構式揹袋(Soft Structured Carrier)和揹架(backpack)三種主要類型。這類揹帶具有較佳承托力，適用於較大/重的幼兒，但售價較貴， 部分設計可能較為笨重，攜帶也較為不便。

腰凳揹帶附有小凳的腰帶設計，外形像腰包，可將嬰兒安放在凳上，方便隨時行走。一些款式還附有肩帶連背墊，增加安全度。這類揹帶使用方便，款式選擇多，但攜帶不便，售價較貴，長時間使用可能增加脊椎負擔。

選購嬰兒揹帶時，要根據產品標示的建議使用年齡和體重進行選擇。由於每個寶寶的體型都有所不同，建議在實際試用後再作最終決定。

對於0至6個月的初生嬰兒來說，他們大多未能自行支撐頭部，因此需要選擇備有頭部承托的款式。同時，揹帶的設計也要能夠良好地承托寶寶的臀部和背部。

將寶寶放入揹帶時，要確保他們的四肢有足夠的活動空間，不受過度束縛。

由於嬰兒皮膚較薄且容易敏感，選擇揹帶時要注重材質的透氣性和舒適度。揹帶不宜過厚，並需要定期清洗，保持衛生。

揹帶的設計要牢固可靠，受力分佈要均勻，以減輕使用者的負擔。同時，操作也要簡單方便，讓使用者能輕鬆將寶寶放入或抱出。

在選購時，可參考歐美和日本的相關安全標準，如歐洲標準EN 13209-2、日本標準CPSA 0027、美國標準ASTM F2236/ASTM F2907等，選擇符合這些標準的產品。

Single shoulder baby carriers feature a diagonal design, mostly made of cotton or blended fabrics, including wraparound, ring sling, and pouch types. Smaller babies can be carried in front cradle style or front facing-in position; larger babies can be carried in front facing-out position. These carriers are lightweight, portable, and affordable but lack weight distribution design, which can lead to shoulder and waist fatigue with prolonged use and restrict baby's leg movement.

Double shoulder baby carriers distribute weight evenly using shoulder and waist straps, including traditional carriers, soft structured carriers, and backpack carriers. These carriers offer better support, suitable for larger/heavier infants, albeit at a higher price point. Some designs may be bulkier and less convenient for carrying.

Hip seat baby carriers come with a waist belt that features a small seat resembling a waist pouch where the baby can be placed comfortably for easy mobility. Some styles also include shoulder straps with back padding for added safety. These carriers are easy to use, offer a variety of styles, but can be cumbersome to carry, more expensive, and may increase spinal strain with prolonged use.

When purchasing a baby carrier, select based on the recommended age and weight indicated on the product. Since each baby's size varies, it's advisable to make a final decision after trying it out practically.

For newborns aged 0 to 6 months who cannot support their heads, opt for carriers with head support. The carrier design should also provide good support for the baby's hips and back.

Ensure that your baby has enough space for limb movement without being overly constrained when placed in the carrier.

Due to babies' sensitive and thin skin, prioritize breathability and comfort when choosing a carrier. Avoid excessively thick materials and ensure regular cleaning for hygiene.

Carriers should be designed securely with even weight distribution to reduce the user's burden. Additionally, they should be easy to operate, allowing users to comfortably place or remove the baby.

When purchasing, consider European, American, and Japanese safety standards such as EN 13209-2, CPSA 0027, ASTM F2236/ASTM F2907, and choose products compliant with these standards.

1. Select a carrier suitable for the baby's age, weight, and growth needs.
2. Babies under 4 months should not be in single shoulder carriers or backpack carriers.
3. Seek assistance from family members for initial use.
4. Ensure adequate support for the baby's head and neck.
5. Operate the carrier in a safe, stable manner.
6. Monitor the baby's movements to prevent injuries or overheating.
7. Regularly change the baby's position and take breaks every 30 to 45 minutes.
8. Avoid running or engaging in vigorous activities while carrying the baby.
9. Check carrier buckles, shoulder straps, and waist belts before use.
10. Minimize bending and stooping movements.
