How can I tell if my newborn baby is getting enough milk?

By: Anne Smith

     One of the biggest concerns that new mothers have is wondering if they will have enough milk for their babies. This concern is the most common reason for starting formula supplementation, and also for early weaning .We live in a society that puts a lot of emphasis on measuring everything, and many of us (and especially our mothers) were bottle-fed, so you knew exactly to the ounce how much milk the baby took in at each feeding.

   You can be assured that nearly all mothers can produce an adequate milk supply for their infant. The human race would not have survived for millions of years if this was not the case. There is a very small percentage of women who just “don’t have enough milk”, but this is highly unusual, and is most often connected to some sort of medical problem, (for example, breast reduction surgery, maternal medications such as birth control pills, or maternal hypothyroidism). Many of these medical problems can be corrected.

    Women have two breasts instead of one so that they can nurse twins.  It stands to reason that the average mother with two breasts will be able to produce enough milk for one baby (at least).

   Since breastmilk intake can’t be measured without using sophisticated scientific equipment, it is important to know how to tell if your baby is getting enough.

    Here are some guidelines to help you assess your baby’s milk intake:

 ---Your milk should “come in” 2-5 days after your baby is born. Your baby is born with extra fluid in his tissues, which is excreted during the first 48 hours after birth. This weight loss usually averages 7-8 ounces. His immature kidneys are not equipped to handle large amounts of fluid during this time. The small amount of colostrum (the sticky yellow fluid that comes out of the breast before the milk “comes in”) is perfect for his newborn system to digest, and provides important antibodies. During the first 24 hours after birth, you usually produce about 37 ml of colostrum (30ml is an ounce).  The baby will get 7-14ml at each feeding, 1/3 to 1/2 ounce each time you nurse.

    Usually on the second or third day, your breasts will start to feel ‘different’: warmer, fuller, and heavier. You will begin to produce transitional milk at this time – a combination of colostrum and mature milk, which will look yellowish. If you don’t feel these breast changes and your baby seems hungry after feedings, consult a health care professional and have your baby weighed.

 ---Your baby should latch on and suck rhythmically for 10-15 minutes on each breast.  He may pause periodically, but should nurse vigorously for most of the feeding.  He should seem satisfied after nursing, and will often fall asleep at the second breast. If he falls asleep and will not take the second breast, try to divide the sucking time between the two sides. If he is sleepy, he will get more milk by nursing for 5 minutes on both breasts rather than 10 minutes on one. You should hear him swallowing regularly while he is nursing.

 ---Your newborn should nurse at least eight times in 24 hours. Many newborns will nurse 10-12 times or more.  This includes longer feedings as well as shorter snacknursings. Nursing every 1 ½ - 3 hours during the day, with one 4 hour stretch at night (if you’re lucky!) works well for many nursing couples.  Don’t expect your baby to be on a 4 hour schedule – the average newborn will not gain enough weight that way. You may need to wake your newborn up for feedings – newborns will often not demand to be fed often enough, especially during the first week or two. (See article on "Waking Sleepy Babies" for more information).

 ---Once your milk is in, your breasts should feel fuller before feedings and softer after you nurse. You may see milk dripping or squirting from one breast while your baby is nursing on the other side. This is a sign that your milk is “letting down”. Your body doesn’t know that you’re not nursing twins, so your milk will let down on both breasts at once. You may or may not feel a distinct sensation associated with the milk ejection, or let-down reflex. Some mothers feel a very strong physical sensation, sort of a tingling, tightening, or pins-and needles response as the milk begins to flow. Some mothers never notice a distinct sensation, and some don’t feel it until they have been breastfeeding for several weeks.

 ---Keep track of your baby’s wet diapers and bowel movements. Other than weight gain, these are probably the best indicators of how much milk your baby is taking in. 

   For the first couple of days after birth, your baby will pass dark, tarry meconium stools. This is the stool the baby has been storing since before birth.  Within a day or two of your milk coming in, his stools will change in both color and consistency. These early transitional stools may be brownish or greenish, and will be loose and unformed (kind of a pea soup consistency).  By the time your baby is 4 or 5 days old, he should be having “milk stools”: Yellowish and seedy, sort of like a mixture of mustard and cottage cheese. He should have at least 2-5 substantial bowel movements in each 24 hour period, and may pass a stool every time he nurses during the first few weeks of life. If he is stooling less frequently, it may mean that he is not getting enough milk.

    During your baby’s first couple of days of life, he will probably wet only once or twice a day, since he is receiving only colostrum.  After the milk comes in, he should wet 6-8 times in 24 hours. It is often hard to tell whether a super-absorbent disposable diaper is wet or not, since the gel inside acts like a wick to draw the moisture away from the surface. You can put a piece of toilet tissue inside the diaper the help you be sure.  The urine should be pale, colorless, and mild smelling.  Dark, concentrated urine may mean that the baby is not getting enough milk.

 ---Most mothers experience some nipple tenderness during the early days of nursing.  The discomfort is usually worst when the baby first latches on, and eases off during the feeding. If the pain is severe, lasts all the way through the feeding, if your nipple tissue cracks or bleeds, or the pains persists beyond one week, it may mean that your baby is not latching on correctly. This can not only cause you extreme discomfort and makefeedings unpleasant, but can also cause your baby to not obtain enough milk.  Check yourbaby’s weight, and consult a breastfeeding specialist who can evaluate your nursing technique. Latch on problems can often be easily corrected.

     The only way to be absolutely sure that your baby is getting enough milk is to check his weight regularly. Remember that it is normal for him to lose 5-7 % of his weight in the first couple of days (doctors often become concerned when weight loss approaches or exceeds 10%). For the average baby, this is close to a half a pound weight loss (often more for larger babies). You need to ask what your baby’s discharge weight is when leaving the hospital, because that is the figure you will be calculating his weight gain from, not from his birth weight.  For example: your baby weighs 7 lbs 8 oz at birth. 48 hours later when you leave the hospital, he weighs 7 lbs 1 oz. Once your milk comes in, your baby should gain about an ounce each day for the first several months of life. Most babies will regain their birth weight within 2-3 weeks .  Many doctors are pleased if the baby has regained his birth weight by 2 weeks , and will do a weight check at that time. I like to see babies regain their birth weight by 10 days, and most babies will do that if breastfeeding is progressing smoothly.  Some doctors check the babies weight around the third day of life, and then make a follow-up appointment for 2 weeks to see if he has regained his birth weight. I strongly encourage mothers to check the weight at about 1 week - at that point, her milk should be in, the baby should have good urine and stool output, he should be gaining weight, and any breastfeeding difficulties can be addressed.  Breastfeeding problems are much easier to remedy if recognized and treated early. Most doctor’s offices will offer free weight checks, since the doctor does not actually have to see the baby at that time (just ask the nurse to put the baby on the scale).  The information you get will be invaluable – either you will know that breastfeeding is going well, and you can relax, or your will know that there is a problem that needs to be addressed and you can take care of it before a little problem develops into a big one.

  One last note on this topic:

      Every mother’s nightmare is that she won’t have enough milk and her baby will become dehydrated. Horror stories abound, and unfortunately, this has (rarely) occurred.  There is absolutely no reason for this to happen if you follow the above guidelines.  True dehydration is an extremely uncommon medical occurrence, and there are warning signs which indicate that your baby needs more fluids immediately. If you notice any of the following symptoms (especially if they occur concurrently with other “red flags” such as low urine and stool output), contact your doctor ASAP.
