Newborn babies are usually given 10-30ml of formula per preparation, about once every 2-3 hours. Depending on the newborn’s stomach capacity and weight, the amount of milk consumed by each newborn baby is different. The amount of formula milk prepared is usually 10-30ml per feeding, about once every 2-3 hours; the amount of milk consumed by a newborn baby with a birth weight of about 3kg may be about 10ml, while the amount of milk consumed by a newborn baby with a birth weight of about 4kg may be about 30ml. In conclusion, the amount of milk consumed by newborn babies varies individually and is related to the newborn’s stomach capacity and weight. The stomach and intestines of newborn babies are weak in digestive function, so they should drink milk regularly and quantitatively, and should not eat too much. In addition, the stomach of newborn babies is in a horizontal position, which can easily lead to spitting up, so try to tilt the child’s body at a certain angle when the child is eating, and burp sufficiently after feeding, which can effectively avoid spitting up of the child’s milk.
