1. Start breastfeeding as early as possible after delivery and insist that the first food for the newborn is breast milk. Start letting your baby suckle on the nipple repeatedly as early as possible after delivery. The first food for babies after birth should be breast milk. If 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. 2. Insist on exclusive breastfeeding within 6 months of age. Exclusive breastfeeding can meet all the fluids, energy and nutrients needed by infants within 6 months of age, so you should insist on exclusive breastfeeding for 6 months. Breastfeed on demand, alternating between the two breasts; breastfeed 6-8 times a day or more. Insist that the infant suckles directly from the breast and does not use bottles to feed artificially expressed breast milk indirectly 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. 3. Conformity feeding, establish a good routine. Breastfeeding should be progressive from on-demand feeding pattern to regular feeding pattern. 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 infant 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, without calcium supplementation. Start daily vitamin D3 supplementation at 10μg (400 IU) a few days after birth. Calcium supplementation is not required for exclusively breastfed infants. Newborns should receive 1mg of vitamin K1 intramuscularly after birth. 5. Infant formula is a desperate choice when exclusive breastfeeding is not possible. Any infant formula is not comparable to breast milk, but can only be used as a helpless choice when breastfeeding fails, or as a supplement to breast milk when breast milk is insufficient. Formula for infants up to 6 months of age is recommended in the following cases: (1) Infants with galactosemia, phenylketonuria, or severe breast milk hyperbilirubinemia. (2) The mother has HIV and human T-lymphotropic virus infection, tuberculosis, varicella-zoster virus, herpes simplex virus, cytomegalovirus, hepatitis B and hepatitis C virus infection, as well as during drug abuse, heavy consumption of alcoholic beverages and smoking, use of certain medications, cancer treatment, and close exposure to radioactive materials. (3) Insufficient milk production despite professional guidance and various efforts. It is not advisable to feed infants within 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. Length and weight are visual indicators that reflect the infant’s feeding and nutritional status. Measure the length and weight of infants before 6 months of age once every half month, and increase the number of measurements during the recovery period after illness. The World Health Organization’s Child Growth Curve is chosen to determine growth. The optimal growth pattern for infants of normal birth weight is to maintain essentially the level of distribution in the group at which they were born. Infants have their own growth pattern and it is not appropriate to pursue the upper limit of the reference value. Infants should continue to be breastfed from 6 months of age and gradually introduce a variety of foods. Supplementary foods are foods of various properties other than breast milk and/or formula. If there are special needs, the addition time of supplementary foods must be adjusted under the guidance of a doctor. 2. Start with iron-rich paste food and gradually add a variety of foods. As the amount of breast milk decreases, gradually increase the amount of complementary foods. First, add iron-fortified infant rice flour, mashed meat and other iron-rich paste foods. Introduce only one new food at a time to gradually achieve food diversity. Supplementary foods should add vegetable oil in appropriate amounts. 3. Promote compliant feeding to encourage but not force feeding Patience feeding, encourage feeding, but never force feeding. Encourage and assist infants and toddlers to eat on their own and develop an interest in eating. Do not watch TV or play with toys during meals, and do not spend more than 20 minutes at each meal. Feeders should have adequate communication with infants and toddlers during meals and not use food as a reward or punishment. Parents should maintain their own good eating habits and become a role model for their infants and children. 4. Complementary foods without condiments minimize the intake of sugar and salt Infant and toddler complementary foods should be made separately. Keep the original taste of food, no need to add extra sugar, salt and various condiments. After the age of 1, gradually try light-tasting family meals. 5. Pay attention to dietary hygiene and eating safety Choose safe, high-quality and fresh ingredients. Always keep the preparation process clean and hygienic, and separate raw and cooked food. Do not eat leftover food, store and dispose of leftover food properly. Wash hands before meals, have adult supervision when eating, and pay attention to the safety of the eating environment. 6. Regular monitoring of physical indicators The pursuit of healthy growth Weight and length are visual indicators reflecting the nutritional status of infants and children. Every 3 months, regularly measure length, weight, head circumference and other physical growth indicators. Smooth growth is the best growth pattern.
