Patient's question:
How much milk should a preterm infant consume at two and a half months? They are 19 days old, and their milk intake is only 70. Is that normal? They stop drinking after consuming 70, and their weight gain is currently very slow.Doctor's answer:
According to the normal stomach capacity of premature infants, calculate the required milk volume: A baby weighing 1 kilogram has a stomach capacity of about 5 milliliters, and a baby weighing 2.5 kilograms can have a stomach capacity exceeding 12 to 15 milliliters. Based on body weight estimation, the initial milk volume can be 2 to 4 milliliters per kilogram of body weight each time. After that, increase by 1 to 2 milliliters per 1,000 grams of body weight each day. Therefore, on the third day after birth, the total milk volume can be maintained between 110 to 120 milliliters, and later it can be kept between 130 to 140 milliliters.
