The younger the child is, the less mature the kidney function is, and the ability to excrete metabolic waste and reabsorb useful substances is not as good as that of adults. In addition, the bladder capacity is small, the diet is mostly liquid, the metabolism is vigorous, and the metabolism of heat energy and water is relatively fast, so the frequency of urination is more.
The exception is the newborn within a few days of birth, and the frequency of urination is less (about 4? 5 times), because the initial liquid intake is less. After six o'clock? 10 days can reach 20 times? 30 times, 6? 12 months old baby is generally 15? 16 times, 2? 3 years old 10 times a day; 4? 8-year-old children are close to adults, about 6? Seven times.
Children's urine output will also be affected by drinking water, sweating, temperature, humidity, food types, activities and mental factors, and there are individual differences.

Generally speaking, newborns begin to urinate on the first day, but the urine volume is small, only 10? 30 ml; Does the normal baby urinate about 400 every day? 500 ml; 1? Three years old is 500? 600 ml; 3? Six years old is 600? 800 ml; 6? 12 years old is 800? 1400 ml.
You can also know whether urination is normal from the color of urine. Normal urine is light yellow and clear. The color of urine is related to the amount of urine, which is clear and colorless and dark yellow. However, it should be noted that the color of urine is related to the amount of drinking water and sweating. Babies who drink more and sweat less have lighter urine, while babies who drink less and sweat more have less urine and darker color.
The transparency of urine is related to the composition of urine, and the composition of urine may be changed when diseases occur, which may affect the transparency. When urethral inflammation occurs, a large number of pus cells and white blood cells appear in the urine, which makes the urine turbid and even hematuria. Need to consider urinary system infection, often accompanied by fever, dysuria, frequent urination and other symptoms.

As for the smell of urine, fresh urine generally has no smell. The longer it is left, the urea in the urine will decompose into ammonia, resulting in bad smell. Urine is composed of 95? 99% of water and other metabolites (such as urea, etc. ), the smell of urine can reflect the health status of human body. If there is any abnormality, we should pay special attention to it. For example, if the child's urine smell is too heavy, he may suffer from hereditary phenylketonuria. If the urine just discharged smells bad, it may be a disease, such as cystitis.
When parents find that the baby's urination is different from the normal situation, don't be too nervous. They can adjust their feeding or environmental factors first. If the baby has physical symptoms, they can ask the doctor to check and decide whether to take medicine or receive other treatment. Because the baby is not easy to express, so usually pay more attention to the situation of urination. When the following abnormal situations occur, they can be handled as soon as possible and given appropriate treatment:
1. Oliguria: It may occur in diarrhea, fever and nephropathy. Attention should be paid to whether to replenish water or not, and some important diseases can also be eliminated through proper inspection.
2. Frequent micturition: Frequent micturition without increasing urine volume may be a pathological cause, such as cystitis, anxiety, fear and other mental factors, which should be further diagnosed as soon as possible.
3. Pain in micturition: It may be caused by urinary tract infections such as urethritis and cystitis. Pay attention to whether there is redness, swelling and pyuria, and urine test can confirm the diagnosis. Finally, remind parents that once the baby's urine is abnormal, or has symptoms of fever, irritability, repeated crying, poor appetite and other unknown reasons, they should go to the hospital in time, which is helpful for the early diagnosis and treatment of children's urinary system diseases.
