Calculate How Much Breast Milk to Put in a Bottle - Babies - 2021

If you are breastfeeding, you have no way of knowing how much breast milk your baby will get each time you breastfeed. So if you don't breastfeed her, how do you know how much breast milk to put in a bottle? How to find out.

Calculation of the amount of breast milk per bottle

You want to make sure that you are not overfeeding your baby when you bottle him or her, here is a 3 step breast milk calculation that can help you figure out how much breast milk your baby should be consuming each time you feed.

equation

Baby's weight in ounces / 6/8 = ounces of breast milk per bottle

Multiply the result by 30 if you want to use milliliters instead of ounces per bottle.

1. Convert your baby's weight to ounces

One pound is 16 ounces, so don't forget to add those extra ounces! For example: if your child weighs 8 pounds 4 ounces, convert 8 pounds to ounces (8 x 16 = 128), then add the four extra ounces (128 + 4 = 132). So your baby weighs 132 ounces.

If you're using kilograms, multiply your baby's weight in kilograms by 35.2 to get ounces. So, a baby weighing 8 pounds and 4 ounces converts to 3.74 kg: 3.74 kg x 35.2 = 132 ounces.

2nd division by 6

Take your child's weight in ounces and divide that number by 6 (132/6 = 22). This number is how many ounces of breast milk your baby should have in a day. Based on the above weight, this child should consume approximately 22 ounces of breast milk in a 24 hour period.

3. Divide by 8

Now you need to ingest the total ounces per day and divide the number of feedings your baby will receive per day. A newborn or toddler should eat at least every three hours, eight times a day. So take the number you just calculated and divide it by 8 (22/8 = 2.75 ounces).

If you prefer milliliters, one ounce = 30 ml. In this case, the baby should consume approximately 82.5 ml of breast milk with each feeding. So, you can add 3 ounces or 90 ml of breast milk to the bottle to feed a baby who weighs 3.74 kg.

How much breast milk does a baby need each day?

Your baby won't get a lot of breast milk on the first or second day because you are only producing a small amount of colostrum. But any amount of colostrum you can pump and give to your baby is beneficial. Between day two and six, your milk production will increase and your newborn may need about 2 to 3 ounces (14 to 28 ounces per day) every 3 hours. From one month and six months, your baby will take an average of 3 to 3 1/2 ounces (25-26 ounces of breast milk daily) every three hours.

Adjusting the amount of breast milk per bottle

Remember that these calculations are only an estimate and a recommendation of the amount of breast milk your child should receive at least every 3 hours. However, some babies may be interested in ingesting more than the calculated amount. As your baby grows and gains weight, you need to adjust your calculations.

You will also need to adjust the amount of breast milk you put in a bottle if you increase the time between feedings. For example, if your child does not bottle every 3 hours to 4 hours, you will need to increase the amount of breast milk in each bottle. So if your baby was taking between 3 and 3 1/2 ounces every 3 hours (8 times a day), adjust the amount in the bottle to approximately 4 1/2 ounces every 4 hours (6 times a day). Of course, if you have any questions or concerns about how much breast milk your child needs, you can always speak to your baby's doctor.

Parts for the storage of breast milk

If you are collecting and freezing your breast milk to bottle feed your baby, it is better to keep your milk in 2 to 4 ounce servings, especially if your baby is younger and does not consume large amounts of breast milk. Storage in smaller quantities avoids waste. It's easy to thaw an additional 2 ounces when you need it. However, if you thaw and warm a container of 6 ounces of breast milk and your baby is taking 4 ounces, you'll have to throw away the extra. As your child gets older and eats more each time they are fed, you can store larger amounts in each container.
