Sometimes babies show no interest while having breast milk. They are very drowsy. Because of which mamas don’t get the amount that their babies really have. 

So, Kaiser Permanente summarized the amount of breastmilk a baby should have per day based on their weight. Also according to research, “in babies aged one to six months, one baby may take as little as 50ml during a feed.”

What are the signs of good breastfeeding?

The signs are quite impressive. Like,

  • The baby is gaining weight as per their age.
  • The feeding needs of the baby are six to eight times per day.
  •  Frequently Wetting the diapers.
  • Looks active, alert, and very content.   

What are the signs of poor breastfeeding?



Slipping on and off the mother’s breast makes the baby fussy. So, don’t be confused with the good feed. How do you know it? There are signs that your baby might not be having enough breast milk,

  • The baby doesn’t look satisfied even after the feeding.
  • Cries a lot.
  • Irritable in nature.
  • If the signs appear then consult your pediatrician about the problem.

How much breastmilk do the breastfeeding babies drink?

The quantity of breast milk the baby takes in each feed, ranges from 54ml to 234 ml. It also highly depends on your baby. How? Some babies have up to 500ml and some are up to 1356 ml a day. Why? If they are getting adequate then they have sufficient.

 Research also says that the milk intake is 19.30oz (570-900 ml) per day. But, the baby’s intake of breastmilk is not changing in between one and six months. It will remain the same. So, you shouldn’t limit it.

Pay attention to the feeding cues and give breastfeeding. At those times babies are more eager to breastfeed. Also in exclusively breastfed babies, the intake of milk increases in the first two weeks of the neonatal period. But, after that, having the milk is the same for six months.

Baby weight (lbs) Breast milk needed (oz) Baby weight (Kg) Breast milk needed (ml)
5 lbs 12 oz 2.0 kg 313 ml
6 lbs 14 oz 2.5 kg 391 ml
7 lbs 17 oz 3.0 kg 469 ml
8 lbs 19 oz 3.5 kg 548 ml
9 lbs 22 oz 4.0 kg 626 ml
10 lbs 24 oz 4.5 kg 704 ml
11 lbs 26 oz 5.0 kg 782 ml
12 lbs 29 oz 5.5 kg 861 ml
13 lbs 31 oz 6.0 kg 939 ml
14 lbs 34 oz 6.5 kg 1000 ml

Note: The values mentioned in the table are average. Not all babies at a specific age consume the same amount of milk. Thus, the average intake values might differ from baby to baby. 

How many times do you have to breastfeed?

If you breastfeed or give it in the bottle by the breast pump, the sessions per day range from 4 to 13. In a single session, the milk expresses about 54 to 234 ml. Its average volume is about 75ml. Anyway, all that depends on your baby’s appetite and the amount of breastmilk is removed from the breast in each session.


What are the ideal daily quantities?

The ideal daily quantities are different between the first day and six months. These days various biological and anatomical changes occur in the baby. These changes are responsible for the milk intake.

In the starting days, the pregnancy hormones and the milk-making hormones start working. And there is a production of small amounts of colostrum. Colostrum is a thick and immune-building antibody. It provides so many benefits for your baby.    


  • On the first and second day, the baby wanted a little breast milk. As his stomach is like the size of a cherry that contains only 5-7 ml.

  • From the second day to the sixth day, the milk production as well as the size of the baby’s stomach increases. So the intake will be 2 to 3 ounces every 3 hours.
  • From 1 month to 6 months of age, the size of the stomach increases from the size of a large egg. It contains 80 to 150 ml. Your baby will take 3 to 4 ounces every 3 hours.

How to estimate the optimal amount of breastmilk?

 There are only 3 phases to estimate the optimal amount of breastmilk as per their weight.


You have to convert the baby’s weight into ounces.

Here 16 ounces refer to one pound. If there are any extra ounces then add them. Let’s take an example;

  • If the baby’s weight is 6 pounds and 2 ounces then the weight will be (6*16 = 96)
  • Now add the extra ounces (96+2=98)
  • So, the baby’s weights 98 ounces.

(if your baby’s weight is in kilograms then multiply it by 35.2. And you will get the weight in ounces)



Divide it by 6

The weight you get in ounces, divide it by 6. By this, you get the total number of ounces per day.

  • 98/6=16.33 ounces in 24 hours.   

Phase -3

Divide it by the number of breastfeeding in a day

In the last phase, take the total ounces in 24 hours and divide it by the number of feeding the baby gets in a day. ( a newborn can take breastmilk at least 8 times a day.)

  • 16.33/8 = 2.04 ounces of breastmilk in each feeding)
