The baby is not fit to eat salt for three months, so please don't add it to the food. This is because breast milk or milk contains natural salt, and it is enough to eat these natural salts. If you add it to food, the baby's kidneys will be affected. Everyone knows that sodium ions in salt need to be metabolized by the kidneys. Children's renal function is relatively poor, and the filtration of glomeruli is not as good as that of adults. If you eat too much salt, it will lead to the impairment of renal tubular excretion and absorption capacity to some extent. Eating more salty food will inevitably increase the burden on the kidneys and affect their normal development.
After three months, with the growth of children and the complete development of renal function, the demand for salt is increasing, and the intake of salt should be appropriately increased. For infants within six months, 200 mg is recommended. 200 mg of sodium is actually equivalent to 0.2 g of salt, but there are some salt points in other foods. Therefore, for babies aged 3-6 months, it is best for mothers to give priority to light foods when making supplementary foods. In fact, there is no need to add salt in particular.
After six months, the baby's kidneys can work normally. Some salt can be added to the baby's food, but the dosage of salt must be controlled below 1 g. Parents are not allowed to take the baby's food and taste it with their own mouths. It is impossible to judge the amount of salt. Whether it is enough or not, it will fall into another misunderstanding and unconsciously cause the baby to eat too much salt. Babies aged one to three should eat as little salty food as possible every day, because eating too much salt is harmful to their health. Babies should develop a low-salt diet, which is very good for their future growth and development. Babies should not eat more salt, and parents should not add it at will.
