When the baby is playing, should he wear open pants or diapers? I believe that parents have their own reasons, but one thing is worth paying attention to: the baby's excretion understanding is complete and mature, and it should be around 2-3 years old. Whether you exercise your baby to wear open crotch pants for a few months to go to the toilet, or wait until your baby is around 2 years old, the time when your baby can really urinate and defecate will not be earlier due to premature exercise. So our parents should not only start from their own perspective, but also consider the baby's warmth, comfort, privacy and other factors, and respect the baby's physiological development characteristics and needs. Let me talk about a section of my experience first. Generally speaking, diapers are composed of three main parts: outer covering layer, absorbent core layer and base fabric. 1. Outer coating layer: close to the baby's body, its main function is to ensure that the urine quickly penetrates and effectively prevent back seepage, so that the surface of the diaper stays dry. 2. Absorbing core layer: The main function of this layer is to capture and quickly absorb urine, disperse urine, or diffuse it into the entire core layer through capillary action, and finally absorb and store urine. 3. Bottom fabric. Many foreign diapers have used non-woven fabrics that feel more warm and breathable. The market price is relatively high. The bottom fabric of domestic diapers is still mainly composed of PE plastic film, which has poor air permeability. One summer day, I took two children for a walk in the park, and suddenly I saw a child squatting down on the corridor in front of me to poop, pulling a large piece of thin stool, which was disgusting. The child was dressed in crotch pants, and his mother squatted aside waiting for him with a toilet paper. The two of them just blocked the tunnel. Before washing machines and diapers were introduced into China, Chinese mothers also had to face a large number of dirty diapers. Since the annoyance is the same, the treatment plan is inevitably similar: like Western mothers, Chinese mothers stop their children from toilet exercises early, that is, traditional pooping. The biggest difference is that the Chinese created open pants. Crotch-open pants once played a certain role, but stepping into the 21st century, understanding the development of infants and young children, with the support of advanced technologies such as diapers and washing machines, in highly cultural urban areas, if we are still guarded to let children excrete anywhere I am afraid that this kind of tradition cannot be explained by reason. Before the creation of diapers, mothers had to wash a lot of diapers every day; before the creation of the washing machine, it was a heavy labor to wash diapers. At present, the absorbent core of diapers on the domestic market is mainly composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP) in a layered structure. Therefore, pediatric experts said with sympathy that it is because of the eagerness to save mothers from washing diapers as soon as possible, the traditional practice of going to the toilet early and ignoring the baby's development has been widely spread.
