Three-month-old baby's urine output decreases

Three-month-old babies usually cannot speak yet, and parents can only judge their children's physical health through their diet, excretion, and mental state. In fact, whether it is a young baby or an older child, you can understand the baby's physical health through these. For example, if the baby suddenly has a decrease in urine volume, most parents are very worried. What is the reason for the decrease in urine volume in a three-month-old baby?

Why does my baby's urine output decrease in three months?

The amount of water a child urinates is related to the amount of water excreted by the kidneys, and the amount of water excreted is related to the amount of water drunk and the amount of water reabsorbed by the kidneys. Children's kidneys are not fully developed and generally reabsorb relatively less, so children generally have more urine. If a child drinks less water and has less urine output, it is normal. If he drinks more but excretes less, this is generally considered a sign of insufficient kidney excretion of water and other waste products, and the baby needs to be taken to the hospital for examination and treatment.

At what age is bedwetting normal for babies

Generally speaking, bedwetting in babies under one year old is a normal physiological phenomenon and mothers don’t need to worry. When the baby is 1 to 1 and a half years old, he will be able to control urination at night, and bedwetting will be greatly reduced. When the baby is 2 to 2 and a half years old, he may not be able to control his urination and defecation very well, so it is normal for him to wet the bed at night.

However, when the baby is 3 years old, with the continuous development of the nervous system, the baby's bladder will naturally control urination and will basically not wet the bed. If a baby over 3 years old wets the bed more than 3 times a week and this continues for more than 6 months, it is not normal and the mother should be vigilant.

Causes of bedwetting in babies over three years old

1. Family inheritance

If either the father or the mother has suffered from enuresis, the baby has a 50% chance of suffering from enuresis; if both parents have a history of enuresis, the baby has a 75% chance of suffering from enuresis.

2. Pinworm disease

If a baby has pinworms, the worms will irritate the urethra and cause the baby to urinate unconsciously at night. In addition, urinary tract infection and kidney disease can also induce nocturnal enuresis.

3. Changes in the environment

When the climate becomes colder, or when the baby drinks too much water before going to bed, or eats too much diuretic fruit, it will change the baby's body environment and increase the incidence of enuresis.

4. Physical defects

Some babies' bodies cannot produce enough urine-controlling hormone ADH when they sleep, which may also lead to increased urine.

5. Long-term use of diapers

If babies use diapers for a long time during infancy and do not develop the habit of regular urination during their growth, they are prone to frequent bedwetting at night.
