First, blindly use the so-called “nutrition” “health care products”. When sitting in the clinic, we often encounter some parents, in order to enhance the child’s resistance, or children because every certain period of time, such as cough, cold, etc., parents usually at home to buy some so-called resistance can improve the “health products”, such as calcium and zinc preparations protein powder and so on to children to eat. There is a proverb that says the most difficult stage for children is “three winters and four summers”. In fact, there is some scientific reasoning. The infant stage, i.e. 3 to 4 years old, is a period of rapid development of the internal organs of the child, as well as a period of rapid growth of the child, the body’s immune function is relatively low, prone to nutrient deficiencies. If the parents do not take care of the child properly, it can cause nutrient deficiencies in the child’s body, including trace elements and vitamins. Usually, children within 2 years of age have a relatively narrow food spectrum, so if they have symptoms of nutrient deficiencies, they can be supplemented appropriately according to the situation, but they must master the principle of “supplementing what is lacking”. Never blindly supplement, because the nutrients in our body are like the principle of leverage balance, but they also affect each other. For example, an excess of zinc will inevitably affect the absorption of copper in the body, which in turn will cause copper deficiency. In addition, some of the “health products” on the market today contain “hormones” that promote appetite in children, often giving parents the illusion of using them. In fact, the long-term use of the child’s future growth and development is harmful but not beneficial. In short, the growth and development of children always follow certain rules, it is impossible to “pull the seedlings to help”; fine, scientific care to reduce the occurrence of pediatric diseases. Second, children’s diarrhea when the use of drugs misconceptions. The etiology of pediatric diarrhea has a certain relationship with the season. For example, in the hot season of summer and autumn, it is easy to suffer from bacterial diarrhea; in the cold weather of autumn and winter, it is easy to have viral diarrhea; and improper diet (such as overeating) is easy to cause indigestion. In the clinic, we often meet parents who go to pharmacies to buy “Mamma Ayi”, “Jin Shuangqi”, or even so-called “anti-inflammatory drugs” such as amoxicillin for their children when they have diarrhea. This is very inappropriate. This is very inappropriate, and sometimes the condition does not improve, but makes the diarrhea symptoms worse, and then the child goes to the hospital. The correct way is to always go to the hospital for diarrhea and to have the stool tested, and then to give the child medicine based on the test results and stool properties. Only bacterial diarrhea can be treated with oral “anti-inflammatory drugs” such as amoxicillin. Probiotic preparations such as “mommy ay” are usually taken when the diarrhea is prolonged or bacterial diarrhea, while other causes of diarrhea are often less effective when taken. In addition, children with diarrhea must pay attention to the avoidance of food, the so-called “three parts of treatment, seven parts of care”. If a child with diarrhea, it is best not to take sweet foods, including sweet staples and snacks. The misconceptions of children’s vomiting medication. Of course, the children’s vomiting referred to here refers to non-jet sudden vomiting that is not accompanied by fever and poor mental response. Sudden vomiting in children is often a symptom of gastrointestinal disorders, some of which can be accompanied by diarrhea, while others are simply vomiting. When sitting in the clinic, I often encounter parents who say, “My child is vomiting while drinking water, or vomiting even when drinking water. The correct approach is for the child not to eat for 1 to 2 hours after vomiting, and if he or she does eat, he or she should only eat a small amount of buns or rolls. After 2 hours the child does not vomit, you can eat some steamed buns or rolls. Of course, because the child will be thirsty after vomiting, they need to drink water, but at this time can only use water to moisten the throat or drink a little. If you drink more or eat thin rice or noodles or the like at this time, the child vomiting will be aggravated. Of course, after the above treatment, if the vomiting still can not be relieved, you can go to the hospital to rehydration, plus some anti-emetic drugs can be. Most of these cases can be cured with just one rehydration. In addition, do not abuse or indiscriminately use “anti-inflammatory drugs” such as amoxicillin.
