Introduction: There is a lot of wrong knowledge about parenting. It is time to abandon the old and backward wrong ideas and believe in science and modern medicine.
STEP 1 Don’t wear too many clothes
Children should wear at most one more dress than adults. Overdressing is not conducive to children’s activities and may also lead to heat-covering syndrome. Avoiding overdressing can reduce the risk of sudden infant death. 
Step 2 Breastfeed
Breastfeeding is economical and convenient, is beneficial to child development, reduces illness and is also beneficial to the mother’s physical recovery. WHO recommends exclusive breastfeeding for 6 months after the birth of the baby, and continues breastfeeding until the age of 2 or more, while supplementing other appropriate foods. 
3. Beware of foreign bodies in trachea and digestive tract
Don’t play with small things that can be put into your child’s mouth, such as coins, buttons, button cell, small magnets, etc. Under the age of 4, avoid the following foods: hot dogs, nuts and nuts, lumps of meat and cheese, whole grapes, soft or hard candy, popcorn, lumps of peanut butter, lumps of vegetables, chewing gum, so as not to cause suffocation. 
4. Sleep on your back and play on your stomach within one year old.
Sleeping on one’s back can reduce the risk of sudden infant death syndrome. When awake, one can play on one’s stomach under the care of adults, which can promote the development of muscles and movements. 
Step 5 Don’t use a walker
Walker cannot help children learn to walk, but greatly increases the risk of accidental injury to children. 
6. Don’t take medicine indiscriminately when you catch a cold.
Cold is caused by virus infection. At present, there is no effective antiviral drug. Cold medicine can relieve symptoms and cannot cure cold. FDA recommends not to give over-the-counter cold medicine to children under 4 years old. If it is not recommended by doctors, it should not be given to children between 4 and 6 years old. These drugs are useless to children and may also cause danger. Children within 3 months should see a doctor for colds. Children over 3 months old should go to hospital for dyspnea, purple lips, ear pain and body temperature exceeding 39 ℃. 
7. Cough does not cause pneumonia.
Cough is a protective reflex, Cough does not cause pneumonia, On the contrary, coughing up phlegm can avoid pneumonia. Cough medicine and cold medicine are used on the same principle. Unless prescribed by a doctor, do not give cough medicine to children under the age of 6. Long-term severe cough may also make children uncomfortable and affect sleep. Drink more water, keep the air moist with a humidifier, and try some honey for children over the age of 1 (to avoid botulinum poisoning, it is forbidden under the age of 1! ).  Children under 3 months old should also see a doctor if they cough for more than 10 days, the cough is getting heavier and heavier, and the sputum is yellow and thick, with blood.
8. Fever is not a bad thing
Fever is beneficial to the child’s condition but can cause discomfort. To deal with fever, we should pay attention to the child’s mental reaction and let the child drink more water. When the temperature exceeds 39.0 ℃ and the child is uncomfortable, we can use antipyretic drugs. The relatively safe antipyretic drugs are ibuprofen and acetaminophen. If something is wrong, we will go to the hospital when we are not sure. How can the child feel comfortable about other things?
9. Diarrhea prevention dehydration is the key
Diarrhea prevention dehydration is the most critical, it is recommended to use hypotonic oral rehydration salt rehydration, continue feeding or increase breast feeding during diarrhea, can give children zinc supplement for 10-14 days. Severe dehydration, bloody stool, frequent vomiting and other conditions should see a doctor as soon as possible.
