Question 1: Breast milk or formula first? When mixed feeding, you should breastfeed on time every day, i.e. breast milk first and then other milk products, so that breast milk secretion can be maintained. In addition to regular breastfeeding, each breastfeeding should not be longer than 10 minutes to avoid baby’s fatigue due to too long time, and then feed other milk products. Question 2: How many times a day should I breastfeed and how many times should I formula feed? If the mother cannot breastfeed during the day due to work, and the milk secretion is also insufficient, she can breastfeed at a specific time every day, usually not less than 3 times, so as to ensure the full secretion of breast milk and to meet the baby’s needs each time. The rest of the times can be given to other milk products, so that the amount of milk fed each time is easier to grasp. Question 3: How can I prevent nipple misalignment? Many parents of newborns worry that their babies will be hungry and give them formula in a bottle, which can cause nipple illusion. If a newborn needs mixed feeding, care should be taken not to use rubber nipples or bottles to feed the baby, but to use a small spoon, cup or dropper to avoid nipple illusion. Question 4: Should I take formula or breast milk at night? Mothers are more tired at night, especially in the latter half of the night, it is troublesome to get up and give formula to the baby, so it is better to breastfeed. When the mother rests at night, the amount of milk secretion is relatively increased and the baby’s need is relatively reduced, breast milk may meet the baby’s need. However, if the amount of breast milk is too little, the baby will not get enough, it will shorten the interval between feedings and affect the rest of the mother and child, and then it will be milk-based. Question 5: Should I feed water to my mixed-feeding baby? Breast milk contains sufficient water, and the water in the formula according to the instructions can also meet the baby’s needs, so in general, mixed-feeding babies do not need to be rehydrated. If in the hot season, the ambient temperature is high, the baby shows signs of thirst, the body temperature is elevated or the skin is blistered, you can feed some water between feedings, 2 to 3 times a day. If the baby refuses, do not force him to drink. Children who are not formula-fed should be given water between feedings because even after dilution, animal milk still contains more protein and minerals than breast milk, and proper hydration can help the kidneys excrete body waste and maintain water balance. Question 6: How to maintain breast milk secretion during mixed feeding? First of all, it is recommended to use the “complementary feeding method” as much as possible, feeding breast milk first and then other milk products, especially at night; make sure that the baby sucks the breast more than 8 times a day and try to empty the breast each time. In addition, the mother should spend as much time as possible with her baby and hold her baby often. When the mother’s milk production increases, she should reduce the amount and frequency of formula feedings. Mothers who work can use the “surrogate method”, but it is best to insist on regular breast pumping while at work.
