A 10-day-old newborn baby drinks about 60ml of milk each time. The amount of milk needed is also related to the baby’s weight and other factors, which need to be adjusted according to the baby’s condition, and breastfed newborn babies need to be fed on demand. The stomach capacity of newborns is small, usually 30~35ml at birth, and about 60ml after 2 weeks. 10-day-old newborns usually drink about 60ml of milk each time. If you are breastfeeding, you don’t need to calculate the standard amount of milk and feed your baby on demand. The amount of milk drunk varies according to the baby’s weight and stomach capacity. The amount of milk can be determined by weight gain, urine output, etc. If the weight gain is about 30g per day and the urine output is more than 6-7 times per day, it means that the amount of milk is sufficient. After breastfeeding, the baby sucks on the nipple and does not let go, and is not at peace after sucking on the milk, etc. This is a sign of insufficient milk supply. If the baby is artificially fed, the amount of milk can be calculated according to the body weight. For example, formula milk for newborn babies usually requires 135ml/(kg-d), and one feeding every 3 hours (i.e. 8 times a day), and then one feeding at night can be gradually reduced to 7 times. It is recommended to choose the appropriate feeding method according to the infant’s needs and milk secretion, and to feed scientifically and reasonably. Any feeding problems are recommended to consult a pediatrician to ensure the child’s ability to grow and develop normally and the nutritional requirements.
