What is the difference between growing pants and diapers? The most obvious difference between them is that there is no elasticity at the waist and there is elasticity at the waist, and the diapers stick to the little belly while the growing pants stick to the sides of the thighs. In fact, these are not the main differences, the main difference is that the growth pants are training pants, like small underwear that can be put on and taken off freely. Once the diapers are on, it is more difficult to take them off. Growing up pants are generally used after the baby turns one year old. After the baby can walk, the baby needs to be trained in urination and defecation, so growing up pants are more convenient, equivalent to putting on a cotton underwear for the baby, which can achieve the purpose of training and prevent the baby from wetting his pants. Although growth pants are more convenient, the price is more expensive than diapers, so it is recommended to choose diapers when you go out.
