Standard 1: fabric comfortThe surface material of high-quality diapers has one feature: it is soft and thin, does not stimulate the skin, and can reduce the friction between diapers and the skin.Judgment skills:You can touch the diaper with your hand and really feel the softness of the diaper, because it directly contacts the skin. It requires softness in hand feeling and fast hydrophilicity in performance to evacuate urine.Standard 2: water absorption and water locking capacityGood diapers usually contain high molecular hygroscopic materials. They can not only absorb a lot of water, but also quickly and firmly lock the water, so that the baby can have a high-quality sleep.Water absorption and water locking capacity test:Pour water into the diapers. If the water is concentrated in the same place, and the interlayer in the middle is kneaded into a ball, and there is back seepage, it means that the guide layer of the diapers cannot diffuse urine, has poor absorption and does not lock water. Gently press the wet diaper with a paper towel. If the paper towel is wetted instantly, it indicates that the reverse osmosis ability of the diaper is poor.Standard 3: instant drying abilityInstant dry diapers can reduce the baby's skin and urine contact, so as to reduce the occurrence of red ass. they are also an essential element to ensure that the baby can get high-quality sleep.Diaper dryness test:Pour the same amount of water into the diapers of different brands, wait for 1 minute after the water is absorbed, then put the paper towel on the water absorption layer of the diapers and press it three times with uniform pressure to compare the wetting degree of the paper towel. The more obvious the water mark on the tissue, the better the dryness of the diaper.Standard 4: breathable and not stuffyThe permeability of diapers must not be ignored. If the air permeability is not good, it will feel very muggy.Air permeability test:You can put the diapers on the hot water cup, and then flip the cup on the diapers. After a period of time, you can observe the distribution of steam in the cup. The more steam, the better the air permeability of diapers.Standard 6: the core is free from faults and lumpsAfter absorbing a certain amount of liquid, if the diaper can still maintain a relatively complete and uniform shape, it is basically judged that the quality of the diaper is relatively good; If after absorbing a certain amount of urine, the inner core of diapers, that is, the absorption layer, becomes loose and agglomerated after extrusion and kneading, it indicates that the quality is poor.Standard 7: three dimensional enclosure, comprehensive leak proofIf the urine pants are erected, it is a bit like the baby's little ass. the three-dimensional protective fence is just guarding the root of the baby's thigh. There is an elastic line to ensure that the urine does not leak out. If not, or the elasticity is not good, it will be pulled to the inner side of the baby's thigh.Standard 8: elastic waistline without bindingThe elastic waistline of diapers can ensure the baby's comfort, but it will not loose and leak urine. If the waist design of diapers is unreasonable, it will strangle the baby.Judgment skills:The mother can stretch the waist circumference of the diaper by hand. If the stretch is good and the elasticity is strong, it shows that it meets the development needs of the baby. If there is a red thigh and the magic patch is loose when the baby moves, it means that the diapers are too tight or too wide.

According to relevant research, children's excretion control muscles generally mature between 12 and 24 months, with an average age of 18 months. Therefore, it is best for the baby to stop using diapers after the age of 3, as long as the baby can go to the bathroom independently.
