Madame ako nababasa dito nagwoworry na kaunti un gatas pagkaanak. Normal lang pala yon kase un capacity talaga ng stomach ni newborn baby ay nasa 1-1.4 teaspoon.
Here's the guide.
Day 1: baby’s stomach holds 5-7 ml (1 – 1.4 teaspoons) at a time. The mother will produce about 37 ml (one ounce) of milk/colostrum in the first 24 hours. The capacity of a newborn’s stomach is influenced by birth weight however the differences are not substantial.
1st week: with frequent feedings milk production increases to about 280 -576 ml (10-19 ounces) per day by day 7. Baby’s stomach can now hold 30-59 ml ( 1 -2 ounces) at a feeding by the end of the week.
2nd & 3rd week: with frequent feedings mother’s milk supply continues to build. Now baby’s stomach can hold 59 – 89 ml (2-3 ounces) at a feeding and baby is taking in 591-750 ml (20-25 ounces) per day.
4th & 5th weeks: babies will now be taking an average of 89-118 ml (3 -4 ounces) per feeding and daily milk intake will be in the range of 750 – 1035 ml (25 – 35 ounces) per day.

Some people have trouble visualizing stomach capacity so using common objects can help make the capacity clearer:
Day 1: 5-7 ml is about the size of a large marble or a cherry
Day 3: 22-27 ml is about the size of a ping pong ball or a walnut
One week: 45-60 ml is the size of an apricot or plum
One month: 80-150 ml is about the size of an large chicken egg
Adult stomach size is equivalent to a soft ball or the size of your own fist clenched at rest and has a capacity of 1-4 liters.
When someone asks you why your newborn is nursing at least 10-12 times in 24 hours and suggests that your milk might not be filling up her tummy you now have some information to help them understand that frequent feedings, on baby’s own schedule, is exactly what her tummy and your milk supply need.
