“What are you afraid of, you also came this way when you were a child!” Whenever you find something wrong with an elderly person’s child care, they always leave you speechless with this statement. Yes, compared to young parents, the elderly have a lot of experience with children, but these “old experience” is still applicable? Some of the “old ways” that old people talk about are really scientific? Can shaving the head prevent heat rash? In summer, you can always see a lot of “little monks”, elders also touch the little monk’s head while saying, “This is the way to be cool in summer, but also to prevent heat rash.” But in fact, this practice is not advisable! The hair is the child’s natural umbrella. Shaving the head in summer does not have a cooling effect. Without the protection of the hair, the baby will lose the natural barrier to shade and block things, accidental injuries, mosquito bites are gathered on the scalp, making the chance of infection greatly increased. In addition, because it is bald, the heat absorbed by the skin will increase, the head sweat will also be quickly lost, not to play a role in the evaporation of heat through sweat, not to mention the bald baby’s head is easy to be sunlight into solar dermatitis. Wearing open crotch pants to be cool? Old people often say that children wear crotch pants to keep cool and convenient. In fact, it is more of a psychological tradition that wearing crotch pants is actually very unhygienic, unsightly, and does not protect the privacy of children. Don’t say children don’t know what privacy is, children’s self-respect and self-love should be cultivated by parents implicitly, not by stubbornness. The World Health Organization has long advocated that sex education should begin at the age of zero, teaching children to protect important parts of their bodies, to respect others, and to love themselves, is part of a healthy psychological development. In addition, crotchless pants make children lose their natural protection as well. The important genital organs are exposed and the child will be in excessive contact with external bacteria when crawling, toddling or even playing, and the urethra and anus are likely to be infected with bacteria and viruses, as well as bumping or rubbing against the genitals, which can also cause damage. In addition, mosquitoes are rampant in summer, and crotch pants are likely to expose the baby’s genitals to mosquito bites, causing insect bite dermatitis. Should babies also drink more water? In principle, the staple food for babies before 4 months of age is mother’s milk or formula, which does not need supplementation. 88% of breast milk is water, which is sufficient for infants’ needs. Formula also does not need extra water, even if it is hot or dry outside. Some doctors will recommend that babies who drink formula need a little hydration if it is hot outside or if they have a fever (but babies will likely prefer to be hydrated through formula). Even more, because the kidneys of children under 1 year of age have not yet reached adult maturity, additional hydration is not advisable, plus. If babies and toddlers before 1 year old are allowed to drink too much water, it will not only cause less milk drinking and slow weight gain, but will also lead to water being excreted from the body in time, when the water content of the blood in the body is too much and the concentration of sodium ions in the blood is too low, which may cause electrolyte imbalance and may seriously lead to conditions such as cramps. Is baby sweating at night a calcium deficiency? Summer is here, sweating at night, is the child weak, kidney deficiency, is the child deficient in calcium? To be able to ask such a question reflects a national condition is that there is a disease called calcium supplementation. Most of the time, children sweat a lot at night because the temperature in the room or the corner where they sleep is too hot. Children themselves have a stronger metabolism than adults, so they should wear less than adults, and especially they should wear less than the elderly. The reason is that the elderly themselves have a slow metabolism and are more likely to feel cold. If you dress your child in accordance with the ideas of the elderly, the child will definitely be muffled. Can’t turn on the air conditioner in summer? As a new generation thing, air conditioning is destined to face various controversies like diapers, but it is necessary to turn on air conditioning for babies properly. Generally speaking, an indoor temperature of about 22-26 degrees Celsius is appropriate, and when the difference between indoor and outdoor temperatures is kept at 5-7 degrees, babies are less likely to get sick when they experience temperature changes. When the air conditioning is on, the baby also does not need to wear too much clothing. The invention of the sleeping bag is also an outstanding representative of the new generation of things, a sleeping bag, an air conditioner, so that children sleep in a comfortable environment, can definitely improve the quality of sleep a few notches. Summer more to wear socks? One of the expert remarks posted on the Internet is this: cold from the bottom of the feet, even in the summer baby also wear socks. Putting socks on babies can play a certain role in keeping them warm and avoiding catching a cold. From the point of view of Chinese medicine and health care, this seems to be the case. But in the modern point of view, it is untenable. One, the child’s feet are covered with perceptual and tactile nerve endings, children can feel the hot and cold changes by playing barefoot, the stimulation of various nerves on the soles of the feet to develop neurological development, after the exercise of the feet is also conducive to promoting the development of the arch of the foot. Second, the weather is hot and muggy, covering the child’s feet is easy to sweat and moist, bacteria are more likely to breed, increasing the risk of infection. Do diapers affect children’s development? Will diapers affect a boy’s testicular development? Will it lead to O-legged and X-legged children? I’m sure you’re not unfamiliar with this topic that once broke out in your circle of friends. Diapers have existed in this society for over fifty years, and there are no reports, either historically or now, that they affect the fertility of baby boys. In medical science, O-leg is called inversion of the knee. It is a deformity in which the inner ankles of the two feet touch each other but the knees cannot come together when the lower limbs are naturally extended or when standing. Most normal babies under 1 year of age have mild internal knee roll. The majority of children under the age of 1 have mild inversion of the knee. 90% of children with developmental inversion of the knee can correct themselves, especially those who walk with their toes pointing inward in an “inward eight” foot, which can be corrected on their own without treatment. The summer urination is good for children? “Don’t you know that you grew up with urination as a child?” The two are very distinctive cultural features, and can be said to be an interdependent community. However, urination has become an old practice that modern medicine has strongly criticized. Urination is not only detrimental to the development of the infant’s hip joint, but also prone to prolapse and anal fissures. Medical research in recent years has increasingly revealed that the traditional practice of urination tends to cause prolapse and eventually hemorrhoids in infants. Studies have also shown that the high incidence of hemorrhoids in China is quite closely related to urination at an early age.
