Weight Gain and Knowing Baby is Getting Enough Milk

In the early days, when the baby is getting colostrum, many mothers don't hear swallows. This doesn't mean that your baby is not getting milk. Often you will be able to see swallows as your baby's jaw drops closer down to his chest for an instant. It is this drop in the chin that tells you that colostrum is going into his mouth; it may look like his suck is deeper and longer. Often babies then rest for a couple of seconds before continuing a pattern of little sucks-dropped jaw-pause.

Human milk is designed with all the nutrients in the right proportions for human babies. Mothers all over the world, eating many types of foods, have similar nutrients in their milk. If a mother is very malnourished her milk can have low amounts of some nutrients, but this is extemely rare in Canada.

Healthy full term breastfed babies gain 150-230 grams (5-8 ounces) per week. They gain weight steadily and quickly in the first four months. Then their weight gain slows down. Some babies may gain slightly less or slightly more depending on their family body structure. This is summarized in a table at the end of the information sheet How to Know Your Breastfed Baby is Getting Enough. Click on the title or contact a local Leader to get a copy.

Yes. You can tell that your baby is drinking by watching for swallowing. When your baby swallows, you will see his chin drop almost to his chest and you may hear a soft "kah" sound. You will also notice that your baby has many slow deep sucks before taking a short pause. When your baby is done, your breasts will feel softer, and your baby will appear satisfied.

Initially babies lose weight. This is mainly because they are expelling the black tarry stool (meconium) that has built up inside the colon during pregnancy. After the meconium is flushed out, the baby's weight will stabilize and the baby begins to gain weight. This most often happens after the third or fourth day. Many babies lose about 7-8% before they start gaining. A baby is expected to return to his birth weight by 10-14 days of age.

Allowing your baby to suckle often and long enough to remove milk are the best ways to establish a good milk supply. Helping your baby obtain a deep mouthful of breast is also important. For more detailed information: Information Sheet #469: Establishing Your Milk Supply  or contact a local Leader.
