| If your baby’s condition is normal, his kidneys have two main functions:|
1. they regulate the outer cellular liquid composition;
2. they provide metabolism products or toxic substances coming out from the organism.
By the moment of baby’s arrival each of his kidneys weights 0, 4 – 0, 5 ounces. Its mass doubles by the age of 5 – 6 months, and it triples by the end of the 12th month of his life.
Baby’s ureter diameter is bigger than adult’s one. But ureter of a newborn child have big amount of curves. The usual ureter’s thickness is less than 0, 2 inches.
Newborn baby’s bladder is little. It is the reason of their often urinating. Newborn’s bladder volume is about one ounce, and at the age of 12 months it becomes about two ounces in volume. During three first days of baby’s life he urinates quite rarely and not much, later he does it up to 15 – 20 times a day.
If you help your little one to get used to a pot, he will urinate into it by the age of 5 – 6 months. But a child can water into his bed up to the age of 3 years, and it is not considered to be a disease yet.
The air temperature influences the amount and frequency of urinations greatly. If it is hot, the amount of urine lessens, but when the temperature lowers, it becomes bigger. The drinking regime is also of a great importance.
