After the baby is born, the milk secreted by her mother in the first few days is called colostrum. Colostrum is small, thick and yellowish.
Compared with mature milk (milk after full moon), colostrum has lower fat and sugar content and is suitable for digestion and absorption of newborns within 10 days after birth.
The yellow colostrum is also rich in protein and vitamin A, which helps to reduce the degree of infant infection, in other words, it can enhance the ability to resist infection.
Growth factors in colostrum can promote infants' immature intestinal development, prepare for the absorption of mature milk, and help prevent allergies and intolerance to certain foods, ie reduce allergies.
Colostrum also has a slight laxative effect, which can facilitate fetal output, reduce bilirubin content, and reduce neonatal jaundice.
The small amount of colostrum necessitates the need for neonatal assimilation. The more frequent this stimulation, the faster the breast milk is produced.
Some people are afraid that the colostrum is dirty and will not be fed. If someone is afraid of the child's hunger, it will be fed with sugar water or other milk. This is not true. Feeding sugar water first will reduce the neonatal demand for breast milk and slow down the milk; feeding other milk may have the potential to plant allergies. According to Dr. Naito Sengchiro, the god of Japanese parenting, even if he only feeds 30 milliliters of milk before opening milk, it is enough to make the child allergic to milk.
