Ways to Tell If Your Baby is Getting Enough Breast Milk

Breastfeeding mothers frequently ask how to know their babies are getting enough milk. The breast is not the bottle, and it is not possible to hold the breast up to the light to see how many ounces of milk the baby drank. Our number-obsessed society makes it difficult for some mothers to accept not seeing exactly how much milk the baby receives.

However, there are ways of knowing that the baby is getting enough. In the long run, weight gain is the best indication whether the baby is getting enough, but rules about weight gain appropriate for bottle-fed babies may not be appropriate for breastfed babies.

Ways of Knowing

As a new mom, you may worry that your baby is not getting enough milk. After all, you cannot tell how many ounces you baby took at one time. But, there are other ways of monitoring your baby's intake. Here are a few examples.

Get to Know Baby's Nursing Style

A baby who is obtaining lots of milk at the breast sucks in a very characteristic way. Babies generally opens their mouths fairly wide as they suck and the rhythm is slow and steady. Their lips are turned out.

At the maximum opening of their mouth, there is a perceptible pause which you can see if you watch your baby's chin. Then, they close their mouth again. This pause does not refer to the pause between suckles, but rather to the pause during one suckle as babies open their mouths to the maximum.

At times, the baby can even be heard to be swallowing, and this is perhaps reassuring, but the baby can be getting lots of milk without making noise. Usually, the baby's suckle will change during the feeding, so that the above type of suck will alternate with sucks that could be described as "nibbling." This is normal.

The baby who suckles as described above, with several minutes of pausing type sucks at each feeding, and then comes off the breast satisfied, is getting enough. The baby who nibbles only, or has the drinking type of suckle for a short period of time only, is probably not getting enough.

This is the best way of knowing the baby is getting enough. This type of suckling can be seen on the very first day of life, though it is not as obvious as later when the mother has lots more milk.

Watch Bowel Movements

For the first few days after delivery, the baby passes meconium, a dark green, almost black, substance. Meconium accumulates in the baby's gut during pregnancy.

Meconium is passed during the first few days, and by the 3rd day, the bowel movements start becoming lighter, as more breast milk is taken. Usually, by the fifth day, the bowel movements have taken on the appearance of the normal breast milk stool, which is pasty to watery, mustard-colored, and usually has little odor.

However, bowel movements may vary considerably from this description. They may be green or orange, may contain curds or mucus or may resemble shaving lotion in consistency (from air bubbles). The variation in color does not mean something is wrong.

Without your becoming obsessive about it, monitoring the frequency and quantity of bowel motions is one of the best ways of knowing if the baby is getting enough milk. After the first three to four days, babies should have increasing bowel movements so that by the end of the first week they are passing at least two to three substantial yellow stools each day.

In addition, many infants have a stained diaper with almost every feeding. A baby who is still passing meconium on the fifth day should be seen at the clinic the same day. A baby who is passing only brown bowel movements is probably not getting enough, but this is not yet definite.

Some breastfed babies, after the first 3 to 4 weeks of life, may suddenly change their stool pattern from many each day, to one every 3 days or even less. Some babies have gone as long as 15 days or more without a bowel movement.

As long as the baby is otherwise well, and the stool is the usual pasty or soft, yellow movement, this is not constipation and is of no concern. No treatment is necessary or desirable for something that is normal.

Generally, small infrequent bowel movements during this time period means insufficient intake. There are definite exceptions and everything may be fine, but it is better to check.

Count Wet Diapers

With six soaking wet (not just wet) diapers in a 24 hours hour period, after about 4-5 days of life, you can be sure that the baby is getting a lot of milk. Unfortunately, the new super dry “disposable” diapers often do feel dry even when full of urine, but when soaked with urine they are heavy.

It should be obvious that this indication of milk intake does not apply if you are giving the baby extra water (which, in any case, is unnecessary for breastfed babies, and if given by bottle, may interfere with breastfeeding).

During the first two to three days of life, some babies pass pink or red urine. This is not a reason to panic and does not mean the baby is dehydrated. No one knows what it means, or even if it is abnormal. It is undoubtedly associated with the lesser intake of the breastfed baby compared with the bottle-fed baby during this time, but the bottle feeding baby is not the standard on which to measure breastfeeding.

However, the appearance of this color urine should result in attention to getting the baby well-latched on and making sure the baby is drinking at the breast. During the first few days of life, only if the baby is well latched on can he get his mother's milk. 

Giving water by bottle or cup or finger feeding at this point does not fix the problem. It only gets the baby out of the hospital with urine which is not red. If re-latching and breast compression do not result in better intake, there are ways of giving extra fluid without giving a bottle directly. Limiting the duration or frequency of feedings can also contribute to decreased intake of milk.

Poor Indicators

Sometimes well-meaning friends will offer advice on how to tell if your baby is getting enough breastmilk. Following are some examples that you should use to gauge whether or not your baby is getting enough.

Having Full Breasts

After the first few days or weeks, it is usual for most mothers not to feel full. Your body adjusts to your baby's requirements. This change may occur quite suddenly. Some mothers breastfeeding perfectly well never feel engorged or full.

Sleeping Through the Night

Some people assume if the baby is sleeping through the night, they are getting enough breastmilk. Not necessarily. A baby who is sleeping through the night at 10 days of age, for example, may, in fact, not be getting enough milk. A baby who is too sleepy and has to be awakened for feeds or who is “too good” may not be getting enough milk. There are many exceptions but get help quickly.

Crying After Feeding

Although the baby may cry after feeding because of hunger, there are also many other reasons for crying. Do not limit feeding times.

Feeding for a Long Time

For one mother every 3 hours or so feedings may be often; for another, 3 hours or so may be a long period between feeds. For one a feeding that lasts for 30 minutes is a long feeding; for another, it is a short one.

There are no rules on how often or for how long a baby should nurse. It is not true that the baby gets 90% of the feed in the first 10 minutes. Let the baby determine his own feeding schedule and things usually come right, if the baby is suckling and drinking at the breast and having at least 2-3 substantial yellow bowel movements each day.

If that is the case, feeding on one breast each feeding (or at least finishing on one breast before switching over) will often lengthen the time between feedings. Remember, a baby may be on the breast for 2 hours, but if he is actually breastfeeding (open-pause-close type of sucking) for only 2 minutes, he will come off the breast hungry.

If the baby falls asleep quickly at the breast, you can compress the breast to continue the flow of milk. Contact the breastfeeding clinic with any concerns, but wait to start supplementing. If supplementation is truly necessary, there are ways of supplementing which do not use an artificial nipple.

Expressing Small Amounts of Milk

Expressing only half an ounce of milk means nothing and should not influence you. Therefore, you should not pump your breasts “just to know”. Most mothers have plenty of milk. The problem usually is that the baby is not getting the milk that is there, either because he is latched on poorly, or the suckle is ineffective or both. These problems can often be fixed easily.

Taking a Bottle After Feeding

If the baby takes a bottle after feeding, this does not necessarily mean that the baby is still hungry. This is not a good test, as bottles may interfere with breastfeeding.

Pulling Away But Still Seems Hungry

A 5-week-old who is suddenly pulling away from the breast but still seems hungry does not mean your milk has “dried up” or decreased. During the first few weeks of life, babies often fall asleep at the breast when the flow of milk slows down even if they have not had their fill.

When they are older (4-6 weeks of age), they no longer are content to fall asleep, but rather start to pull away or get upset. The milk supply has not changed; the baby has. Compress the breast to increase flow.

Understanding Scales and Weights

Scales are all different. We have documented significant differences from one scale to another. Weights have often been written down wrong. A soaked cloth diaper may weigh several hundred grams (half a pound or more), so babies should be weighed naked.

Many rules about weight gain are taken from observations of the growth of formula-feeding babies. They do not necessarily apply to breastfeeding babies. A slow start may be compensated for later, by fixing the breastfeeding. Growth charts are guidelines only.​
