Breastfeeding Trivia: 16 Random Facts

Breastfeeding Trivia: 16 Random Facts

Random facts we have learned about breastfeeding:

1) In the first 24 hours of life, a breastfed baby takes in about 7 – 14 ml. (That’s 1 ½ to 3 teaspoons of milk!)

2) Breast milk is made up of about 87% water. (Hence the recommendation that breastfed babies do not require extra water supplements.)

3) The time it takes for half of the milk to leave the stomach of a breastfed baby: 47 minutes. The time it takes for half of the milk to leave the stomach of a formula fed baby: 65 minutes. (Van den Driessche 1999)

4) By the time a breastfed baby is 8 months old, the baby will have consumed about 30,000 kcal less than a bottle fed baby.

5) In the first 3 months of life, it is normal for a breastfed baby to have more fat than a non breastfed baby. From 3 to 12 months, however, the breastfed baby will be leaner.

6) Most women experience “breast fullness” at about 3 days postpartum. Insulin dependent diabetic moms may need an extra 24 hours for this fullness to occur.

7) Introduction of cow’s milk protein in the first 8 days of a baby’s life increases the risk for Type 1 diabetes.0-5

8) Moms who have breastfed at least one other child will produce more milk than a mom who is breastfeeding her first baby.

9) A woman’s right breast usually produces more milk than her left.

10) Some women’s breasts have a larger storage capacity. Their babies, therefore, may be able to go longer between feeds.

11) When a woman is weaning her baby, her breast milk will be higher in sodium and therefore taste saltier.

12) There has never been a documented case of a baby being allergic to its own mother’s milk.

13) The amount of cholesterol in breast milk increases as the baby gets older. Formula contains little to no cholesterol. Cholesterol plays an important role in nerve conduction in the brain.

14) 50% of the available iron is absorbed from breast milk. 7% of the available iron is absorbed from iron fortified formula.

15) Women lower their risk of osteoporosis the more babies they have and the longer they breastfeed.

16) Extreme exercise may increase the lactic acid in breast milk. It is not harmful, however, a baby may not like the taste.

    I thought that breast size (because it reflects adipose, not glandular tissue) was unrelated to storage capacity?

    Good question, Sarah!
    We have re-looked at the text “Core Curriculum for Lactation Consultant Practice” page 489-490. The actual wording is “larger breast storage capacity” (capacity = “how much milk the glandular tissue in her breasts can comfortably hold”). Cindy may have misinterpreted the meaning. Good thing this wasn’t on the exam!
    We have amended the wording in our post.
