1. Start breastfeeding as early as possible after delivery and insist that the first food for newborns is breast milk. Start letting your baby suckle repeatedly on the nipple as early as possible after delivery. The first food for babies after birth should be breast milk. As long as the weight loss after birth does not exceed 7% of the birth weight, you should insist on exclusive breastfeeding. Babies should not be overly wiped or sterilized before suckling. Ancillary factors such as a warm environment, pleasant mood, mental encouragement, and breast massage can help smoothly and successfully start breastfeeding. When the baby is just born, the new mother does not have much milk, and at this time many parents are anxious to add milk powder to the baby, in fact, the baby’s demand for milk in this period is not much, and the baby is part of the energy reserves at the time of birth, to provide the baby’s energy needs within three days after birth, as long as the baby’s weight loss after birth is not less than 7% of the birth weight is normal, so mothers and fathers should not be anxious to add milk powder to the baby. Breastfeed on demand, alternating between both breasts; breastfeed 6~8 times a day or more. Insist that infants suckle directly on breast milk and do not use bottles for indirect feeding of artificially expressed breast milk whenever possible. If special circumstances require the addition of complementary foods before the age of 6 months, a decision should be made carefully after consulting a doctor or other professional. Ms. Zhu has contacted many new mothers who have the misconception that they will feed both breasts at each feeding. In fact, the alternate feeding of both breasts mentioned here refers to the fact that different breasts should be chosen for the two feedings before and after, not that the two sides should be switched during a single feeding. Milk is divided into foremilk and hindmilk, the main component of foremilk is lactose and protein, and the main component of hindmilk is fat. If you choose to suck on both sides in rotation for a single feeding, the fat content that your baby takes in will not be enough, then your baby will be hungry faster and will need to be fed more often, and if the fat intake is too low, your baby’s weight gain will also be affected. Therefore, be sure to insist on one side of the breast sucking after each feeding before changing to the other side. 3, compliant feeding, develop good habits Breastfeeding should be progressive from on-demand feeding mode to regular feeding mode. Feeding should be done promptly when hunger causes crying. Do not force the number of feedings and time, but generally the number of feedings per day may be more than 8 times, and initially after birth it will be more than 10 times. As the baby gets older, gradually reduce the number of feedings and establish good eating habits with regular feedings. If the baby cries abnormally, non-hunger causes should be considered and active medical attention should be sought. 4. Start vitamin D supplementation a few days after birth, no calcium supplementation Infants should start taking vitamin D3 supplementation of 10μg (400 IU) daily a few days after birth. Calcium supplementation is not required for exclusively breastfed infants. Newborns should be given intra-muscular injections of vitamin K11mg after birth. It is recommended to start VD supplementation at around 15 days for exclusively breastfed babies to promote calcium absorption. If the baby is mixed fed or artificially fed, you should calculate the VD intake of the baby according to the amount of formula milk per day before considering whether you still need to add VD, the total amount of 400IU per day can be. 5.Infant formula is a helpless choice when exclusive breastfeeding is not possible. In the following cases, it is recommended to use formula suitable for infants from 0 to 6 months of age: a. Infants with galactosemia, phenylketonuria, severe breast milk hyperbilirubinemia. b.Mothers with HIV and human T-lymphotropic virus infection, tuberculosis, varicella-zoster virus, herpes simplex virus, cytomegalovirus, hepatitis B and hepatitis C viruses during infection, as well as drug abuse, heavy consumption of alcoholic beverages and smoking, use of certain drugs, cancer treatment and close exposure to radioactive substances. c. Insufficient milk production despite professional guidance and various efforts. It is not advisable to feed infants from 0 to 6 months of age directly with ordinary liquid milk, adult milk powder, protein powder, soy milk powder, etc. 6. Monitor physical indicators to maintain healthy growth Body length and weight are visual indicators reflecting the feeding and nutritional status of infants. Infants should be measured for length and weight once every six months before 6 months of age, and the number of measurements can be increased during the recovery period after illness, and the World Health Organization’s “Child Growth Curve” should be used to determine whether infants are fed correctly and reasonably. 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.
