1. Use toothpaste skillfully: If there is a small area of skin injury or burns, applying a little toothpaste can stop bleeding and relieve pain immediately and prevent infection, and the curative effect is quite good.
2. Skillfully remove the greasy screen window: You can put the washing powder and cigarette butts left over from smoking together in the water, and use them to clean the glass window and screen window after dissolution, which has a good effect.
3. Put the shrimp in a bowl, add a little salt and edible alkali powder, rub it with your hands for a while, then soak it in clear water, and then wash it with clear water. This will make the fried shrimps transparent as crystal, refreshing and delicious.

Babies of all ages are anaemic. When the baby is anemic, some of it is accompanied: the skin and nail bed are pale in the early stage of chronic anemia.
In severe anemia, the skin is often waxy yellow, and the elderly often have symptoms such as fatigue, dry hair, malnutrition and physical retardation. Physical examination can find that the heart rate is accelerated, the pulse is strengthened, the arterial pressure is increased, and sometimes capillary pulsation can be seen.
Babies often show listlessness, inattention and excitability. The baby's nutrition in the fetal period comes entirely from the mother, especially in the last few weeks of the middle period. With the enhancement of fetal hematopoietic activity and the need to store enough iron for hematopoiesis after birth, more iron is needed to be provided by the mother.
Therefore, it is one of the important factors to ensure that pregnant mothers consume enough iron and pay attention to choosing foods with more iron. After the baby is born, iron supplementation is replaced by breast milk or breast milk.
The key to prevent baby anemia lies in diet. 1 infant feeding under one year old.
If breast milk is sufficient, try not to add milk or other milk substitutes within 4 months to reduce the interference of other foods on iron absorption in breast milk. Breastfeeding should last at least 4 months, preferably 6-9 months.
From the second month, fresh orange juice or vitamin C50~ 100 mg can be added after breastfeeding. For full-term babies, iron should be supplemented every kilogram of body weight 1 mg every day after 4 months.
It is best to use nutrient solution containing iron and vitamin C, and artificially feed babies with iron-containing milk.
Add solid food after 5~6 months. 6~7 months, add meat, minced fish, liver mud, etc. Add the right amount of iron.
It is best to maintain iron supplementation until l~2 years old. However, taking iron fortified foods should prevent deterioration and accidental poisoning.
2~3-year-old baby, ensure that there are enough animals and beans every day. Such as chicken, duck, pig blood, shepherd's purse, seaweed, kelp and so on.
Let the baby eat more fresh fruits to help iron absorption. Danger signal: when severe anemia compensates for dysfunction, the baby will have heart enlargement, heart murmur and even congestive heart failure.
The baby has obvious loss of appetite, frequent nausea, abdominal distension or constipation, occasional glossitis and atrophy of the tongue. Acute anemia can lead to shock.
Prevention: insist on breastfeeding, iron in breast milk is easy to be absorbed and utilized. Add iron-rich complementary foods according to the age of the month: egg yolk, fish, liver mud, minced meat, animal blood, green vegetable mud, tofu, etc.
The absorption and utilization rate of iron in animal food is higher than that in plant food. Spinach contains more oxalic acid, which hinders the absorption of iron. Boil and filter before eating.
Advocating cooking with iron pots and shovels can increase the supply of iron. Babies with severe anemia can eat iron-fortified foods such as soy sauce, biscuits and flour under the guidance of a doctor.
Hemoglobin should be measured regularly. /kloc-babies under 0/year-old can be measured every three months, 1 year-old once in the second half of the year, and once every year after 2 years old, and the weight of 1 time should be measured once a month. Find out why they don't gain weight. Coping method: pay attention to diet therapy. The quality and quantity of diet depends on the baby's age and illness.
The main drugs for anemia are iron, vitamin B 1 and folic acid. Iron is only suitable for the treatment of iron deficiency anemia, and vitamin Bl and folic acid are suitable for nutritional megaloblastic anemia.
Severe anemia or cardiac insufficiency caused by anemia, blood transfusion is a rescue measure. Love tip: Baby anemia is easy to be complicated with acute and chronic infection, malnutrition, digestive system disorder, etc., which requires special attention.
Female baby bleeding is a special physiological phenomenon, but some of them also belong to gynecological diseases. A small number of female babies who gave birth 5-7 days later found a small amount of bloody secretions when changing diapers for 1-2 days. At this time, the estrogen in the mother is transmitted to the fetus through the placenta, which makes it affected by estrogen after birth, leading to increased secretion.
If the baby eats milk, sleeps and urinates normally, parents don't have to be nervous, change diapers frequently and keep local cleanliness. If the amount of bleeding is large, the secretion smells bad and lasts for a long time, accompanied by bleeding in other parts, you must go to the hospital in time.
Some female babies will have intermittent bleeding in infancy. Experts pointed out that the causes of female baby vulva and * * * bleeding can be divided into hormonal and non-hormonal two categories. Hormone bleeding is mainly precocious puberty, which is relatively rare; Non-hormonal bleeding accounts for about 80%, so parents should pay attention to it.
The main reasons are as follows: 1. * * * Foreign body: Out of curiosity or to relieve vulvar itching, children often insert hairpins, pins or small toys into * * *, especially rural children who wear open-backed pants and sit on a pile of wheat and rice. When wheat or millet enters * * *, foreign bodies will stay in * * *, which will generally cause inflammation. When children suffer from nonspecific and bacterial inflammation, especially those who are refractory for a long time, the possibility of foreign bodies in * * * should be considered.
2. Traumatic bleeding: Children are more active than adults, and their awareness of self-protection is poor. Surgical vulvar bleeding caused by trauma is more common. Generally, * * * falls from a height or touches the corner of a stone, iron or stool. Some people may get bruised when urinating in spittoons. After vulvar injury, local pain, some produce hematoma, some produce vulvar skin laceration, and even oral mucosa laceration. The amount of bleeding varies.
3. Vulva inflammation: In infancy, girls' vulva is underdeveloped, with low estrogen level and strong epithelial resistance, and * * * is adjacent to * *, which is prone to bacterial infection and inflammation. Pathogens can be spread through the clothes, tubs and hands of sick mothers, nurses or kindergarten children, and can also be caused by poor sanitary conditions, unclean vulva and frequent pollution of feces.
Symptoms are mostly vulvar swelling, itching, purulent secretions, and some are repeated bleeding. Warm tips from well-known experts of Early Education Network: In recent years, gonococcal vulvar inflammation has occurred through indirect transmission of * * *, which should arouse vigilance.
In recent years, children's gynecological diseases have attracted more and more attention. If parents have questions in this regard, they can go to the Pediatric Gynecology Department of Beijing Children's Hospital.
