For various reasons, many young mothers nowadays have just had their babies and are inexperienced. So, they are faced with a problem, how to feed the baby, so that the baby grows faster and better? 1, after giving birth as early as possible to open the milk, insist that the first food for newborns is breast milk Colostrum is rich in nutrients and immunologically active substances that help the development of intestinal function and provide immune protection. After delivery, the mother should start breastfeeding as early as possible so that the baby can start sucking on the nipple to obtain colostrum and further stimulate lactation and increase milk secretion. The infant’s first food after birth should be breast milk to help prevent infant allergies and to reduce the incidence of neonatal jaundice, weight loss and hypoglycemia. In addition, allowing the infant to suckle repeatedly on the nipple as early as possible is the key to ensure successful exclusive breastfeeding. When babies are born, they have certain energy reserves in their bodies to meet their metabolic needs for at least three days, so there is no need to worry about newborns’ hunger during the process of breastfeeding. Ancillary factors such as warm environment, pleasant mood, spiritual encouragement and breast massage can help smooth and successful initiation of breastfeeding. Preparation for breastfeeding should begin during pregnancy. 2. Insist on exclusive breastfeeding within 6 months of age Breast milk is the most ideal food for infants, and exclusive breastfeeding can meet all the fluids, energy and nutrients needed by infants within 6 months of age. In addition, breast milk is conducive to the establishment of a healthy intestinal micro-ecological environment and maturation of intestinal functions, reducing the risk of infectious diseases and allergies. Breastfeeding creates an environment of emotional communication between mother and child, giving infants the greatest sense of security and facilitating their psycho-behavioral and emotional development, and breastfed babies are the smartest. Breastfeeding is economical, safe and convenient, and helps to avoid maternal postpartum weight retention and reduces the risk of maternal breast cancer, ovarian cancer and type 2 diabetes. Exclusive breastfeeding should be adhered to for 6 months. Breastfeeding requires the efforts of the whole society, technical guidance from professionals, and active support from families, communities and workplaces. Make full use of policies and laws to protect breastfeeding. 3, compliant feeding, develop good habits Breastfeeding should be compliant with the maturation of the infant’s gastrointestinal tract and the growth and development process, from on-demand feeding pattern to regular feeding pattern progression. Infant hunger is the basis of on-demand feeding. Infants should be fed promptly when hunger causes crying, generally 6~8 times a day or more. Parents should clearly perceive the time information of their infants’ feeding pattern. As the age of the baby increases, the volume of the baby’s stomach gradually increases, the amount of milk intake increases, the feeding interval is extended, and the number of feedings decreases, gradually forming good eating habits with regular feeding. If the infant’s crying is obviously not in line with the usual feeding pattern, you should first rule out non-hunger causes, such as gastrointestinal discomfort. If the baby is crying for non-hunger reasons, increasing the number of feedings can only relieve the baby’s anxiety, but cannot solve the fundamental problem. The vitamin D content of human milk is low, and breastfed children do not get sufficient vitamin D. Suitable sunlight exposure will promote the synthesis of vitamin D in the skin, but given the limitations of parenting, sunlight exposure may not be the most convenient way to obtain vitamin D for infants within 6 months of age. Daily vitamin D supplementation of 10 μg (400 IU) should be initiated within days of birth. Exclusive breastfeeding can meet the infant’s calcium requirements for bone growth without additional calcium supplementation. Vitamin K supplementation is recommended for newborns after birth, especially for newborns delivered by cesarean section. 5.Infant formula is a helpless choice when exclusive breastfeeding is not possible Due to certain metabolic diseases in infants, infectious or mental diseases in mothers, insufficient milk production or no milk production, etc., when infants cannot be fed with exclusive breast milk, it is recommended that formula feeding suitable for infants 0?6 months of age is preferred, and it is not advisable to feed infants directly with ordinary liquid milk, adult milk powder, protein powder, soy milk powder, etc. Any infant formula is not comparable to breast milk and can only be used as a helpless choice after the failure of exclusive breastfeeding or as a supplement to breast milk after 6 months of age. giving up breastfeeding before 6 months of age and choosing infant formula is detrimental to the health of the infant. 6. Monitor physical indicators to maintain healthy growth Length and weight are visual indicators that reflect the infant’s feeding and nutritional status. Infants should be measured for length and weight once every six months before the age of six months, and the number of measurements can be increased during the recovery period after illness. Infants have their own growth pattern, too fast or too slow growth is not good for children’s long-term health. There are individual differences in infant growth, and there are also periodic fluctuations, so there is no need to compare growth indicators with each other. Breastfed children may have lower weight gain than formula-fed children, but as long as they are on a normal growth trajectory, they are in a healthy growth state.
