After birth, your baby’s milk needs gradually increase as he or she develops and grows physically. There is a certain pattern until complementary foods are added at 4-5 months. Early newborn babies just start to breastfeed, generally between 3-5ml per meal, and should have 6-8 meals per day; 5-10ml per meal in the middle term; 10-20ml per meal can be reached at the end of the newborn period, when the newborn should have 6 meals per day, so the total amount is between 80-100ml. 2 months old, with the increase of appetite, the amount may increase about 10ml per week, and can generally reach 20-30ml per meal. After 3 months, the amount of milk can reach between 30-50ml per meal, so the daily amount of milk should be between 200-300ml. after 4 months, the amount of milk can generally reach between 100-150ml per meal, and the daily total can be between 400-500ml. after 5 months, the amount of milk can generally reach 150-180ml per meal. at this time Babies start to add complementary foods, so the amount of milk used afterwards will be in a certain proportion to the complementary foods and will no longer have a certain pattern of change, but in general can remain relatively stable.
