At the age of one month, the amount of formula fed varies from person to person, just as everyone has different heights and weights. In general, they feed between 120 ml and 150 ml per feed and need to feed 6 to 7 times a day. However, every baby is unique, and their appetites and needs are different. Therefore, the specific amount of milk powder feeding needs to be determined according to the actual situation of the baby. 
Some babies may have a greater need for formula, while others may have a smaller need. It's like different members of a big family, some kids like to eat more food and others eat less. When feeding milk powder, be sure to follow the doctor's advice, follow the instructions on the milk powder package, and never change the concentration or frequency of the milk powder at will. Otherwise, it may affect your baby's health. 
In addition, the interval between feedings is also very important. In general, newborns need to be fed formula every three to four hours when they are one month old. If your baby is crying between feedings, it may be because he is hungry or needs a diaper change. It's like an adult who gets irritable and crying if he's hungry or unwell. 
In short, the amount of newborn milk powder feeding varies from person to person and needs to be determined according to the actual situation of the baby. At the same time, the interval between feeding milk powder should also be paid attention to ensure the health and growth of the baby. Only in this way can we provide a warm, comfortable and healthy environment for the baby.
