The baby just born, so weak and lovely, should be very careful when feeding, because at this time, the development and function of the digestive and metabolic organs of the newborn are not mature and relatively weak, but they have the ability to digest and metabolize breast milk from the moment of birth.
With the growth of age, the digestive and metabolic functions of baby tend to mature. Therefore, we need to carry out reasonable nutrition feeding according to the characteristics of baby's digestion and metabolism, so as to meet the needs of baby's growth and development.
Why is not the stronger the better?
Exploration: after the food is absorbed in the intestine, most of the metabolic waste will be discharged from the body through the kidney. However, the development and function of the kidney in infancy is not mature, and the regulation ability of nutrient metabolism is limited. If the osmotic pressure of food and the solute load of kidney are too high, it will cause vomiting, diarrhea, dehydration and other manifestations.
To do so: when preparing the formula for the baby, it should be prepared strictly according to the instructions. It is not allowed to prepare too thick formula to increase nutrition, because the higher the concentration, the less water, the higher the solute load of the milk's kidney, and the heavier the burden on the kidney. In addition, fresh milk due to the high protein and mineral content, will increase the renal solute load, generally do not let the baby eat less than 2 years old.
Why don't newborn babies eat too much?
Exploration: the stomach capacity of infants is small, 30-35 ml for newborn infants, 100 ml at 3 months, 250 ml at 1 year old, and 500-600 ml at 3 years old.
Do this: when feeding the baby, the amount of milk and food should not be too much each time. The best way to judge whether a baby is eating enough is to see the growth of height and weight, whether it is growing continuously and whether it is within the normal range.
