There are significant differences between pull-up pants and diapers in many aspects. The following is a detailed comparative analysis:

1. ‌Design Differences‌
Pull-up Pants‌: They look similar to small underwear, but with elastic materials on the waist and thighs, which provide better overall wrapping and fit the baby's body curves, reducing friction and marks during activities. ‌
‌Diapers‌: They are sheet-shaped, fixed with Velcro on the waist, and can be adjusted in tightness, but they have less elasticity and may cause pressure on the skin.

2. ‌Applicable Age and Activity Needs‌
‌Pull-up Pants‌: They are recommended for babies over 6 months old who can roll over, crawl or learn to walk, which is convenient for activities and helps with toilet training. ‌
‌Diapers‌: They are suitable for babies from newborns to about 2 years old who are less active, especially at night or when the urine volume is large.

3. ‌Putting On and Taking Off‌
‌Pull-up Pants‌: They can be put on directly like underwear, and can be operated while standing or lying down. When taking them off, just tear open the two sides, which is suitable for active babies. ‌
‌Diapers‌: They need to be fixed by Velcro when lying flat, and parents are required to put them on and take them off. They are more flexible to adjust but more complicated to operate.
4. ‌Performance and Price‌
‌Absorbency‌: Diapers usually absorb more water and are suitable for babies who urinate a lot; pull-up pants absorb less water but are designed to be more leak-proof. ‌
‌Price‌: Pull-up pants are generally more expensive than diapers due to their complex design. ‌
5. ‌Other Considerations‌
‌Leak-proof effect‌: Diapers have better three-dimensional guards for leak-proofness, while pull-up pants may be slightly inferior during intense activities. ‌
‌Transitional use‌: Some parents will mix the two, such as using pull-up pants during the day for easy activities and using diapers at night for enhanced absorption. ‌
‌Summary‌: The choice should be based on the baby's age, activity level and economic budget. If the baby is in the toddler stage or resists lying down, pull-up pants are preferred; if high cost-effectiveness or strong moisture absorption is required, diapers are more suitable.
