A common worry among breastfeeding mothers is whether their baby is getting enough milk because they can’t see how much they have drunk. And, because breast milk is very quickly and easily digested—it can be digested in one hour 1—a breastfed baby might ask to breastfeed again (and again) even though they were just fed, causing mothers to worry about their milk supply. Fortunately there are several ways for parents to check whether their babies are getting enough milk:
#1 Milk coming in
After the birth, your breasts will contain small amounts of colostrum (the first breast milk). These small volumes are perfect for your healthy newborn baby to learn to breastfeed and will keep them hydrated 2. Most mothers notice their milk “comes in” around two to three days after their baby is born. Breasts will feel fuller, heavier and warmer and you may notice one breast leaking while your baby feeds from the other side. If you haven’t noticed a feeling of your milk coming in by the fourth day, ensure your baby has been weighed and checked by a health professional 3 and contact your breastfeeding specialist to check for any potential reasons for a delay in your milk supply.
#2 Look and listen for swallowing
When your baby is breastfeeding well you will see his jaw moving vigorously throughout the feed (expect this to be at least ten minutes or more on each breast) and you will either hear him swallowing, or see the pause in his suck while he swallows breast milk. Dr Jack Newman, a canadian paediatrician and breastfeeding specialist explains:
When a baby is getting milk (he is not getting milk just because he has the breast in his mouth and is making sucking movements), you will see a pause at the point of his chin after he opens to the maximum and before he closes his mouth, so that one suck is (open mouth wide > pause > close mouth type of sucking).
If you can’t hear or see your baby swallowing milk and they appear to be mostly just sleeping at the breast, try some breast compressions (a type of breast massage) during a breastfeed and seek breastfeeding help from an IBCLC lactation consultant as soon as possible.
#3 Count the dirty nappies
What goes in must come out! If your baby is swallowing plenty of breast milk there will be plenty of breastfed baby poop to match. Several dirty nappies each day containing soft yellow or mustard coloured poop by day four or five are a good sign that your baby is feeding well. About six wet nappies per day, with pale coloured urine, alongside the dirty ones show your baby is well hydrated—but wet nappies alone are not confirmation that your baby is getting enough milk in the first six weeks. See Breastfed Baby Poop for more information about the amount of poop to expect as your baby grows and the colour changes that are normal during the first five days.
After the first three to four days, the baby should have increasing bowel movements so that by the end of the first week he should be passing at least two to three substantial yellow stools each day. In addition, many infants have a stained diaper with almost each feeding.
Nappies with red marks or a “brick dust” appearance after the fourth day could be a sign your baby isn’t getting enough milk, contact you baby’s doctor and seek help with breastfeeding.
#4 Monitor your baby’s weight
The first two to four days
It is normal for a breastfed baby to lose a little weight before his mother’s milk comes in during the first two to four days of life and babies are well equipped for this. A loss of 5‑7% weight is usually accepted as normal although more research is needed 4. If your baby has lost more than 5‑7% of their bodyweight or is still not gaining weight after 2‑4 days contact your breastfeeding specialist to review how breastfeeding is going.
After the first few days
Once your milk has come in, a weight gain of 30‑40g per day (or 7‑10 ounces per week) in the first three months shows your baby is growing well5. This slows down between 3‑6 months to an average gain of 20g per day.
Getting a weekly weight check on the same scales and plotted on your baby’s WHO growth chart6 will show how your baby is growing. Advice to weigh monthly is only appropriate once your baby is thriving and gaining weight and you know breastfeeding is going well. However, a month is too long to leave a baby who is hardly gaining, not gaining or who is losing weight. If your baby is not gaining weight in the normal range stay in touch with your health professional to rule out any underlying medical conditions, contact an IBCLC lactation consultant and see Baby Not Gaining Weight and Understanding Your Baby’s Weight Chart for further information. The earlier you seek help the easier it will be to protect your breast milk supply and the quicker to get breastfeeding back on track.
#5 Look for signs of satiety
Signs that your baby is full include his falling asleep or letting go of the breast of his own accord after about 10-30 minutes of active sucking and swallowing. There is no need to time it, and he may need to feed again quite soon, but when he has had enough milk he will usually be very relaxed with open hands and a relaxed expression, often described as looking “milk drunk”. Conversely, a hungry baby tends to hold himself quite tensely with clenched fists, arms bent and a worried expression. A hungry baby may try to feed constantly and never seem satisfied or sometimes he may sleep all the time and not have enough energy to feed.
Avoid a dummy
Avoid giving your baby a dummy or pacifier until breastfeeding is well established otherwise you might miss feeding cues and your baby may not get enough feeds.
#6 Breastfeed often
Your baby is trying to double his weight in the first few months of life so he needs plenty of breast milk to do that. The more often you breastfeed (with good positioning and plenty of swallows) the more milk will be made. Follow your baby’s lead even if he has only fed half an hour ago. In the early weeks your little one will breastfeed at least 8 to 12 times in a 24 hour period, including night feeds which are very important. A baby can take 30% of his calories at night. See One Breast or Two Per Feed? to explain whether to offer one breast or both at each feed and How Often Should a Newborn Feed?
Early feeding cues
Crying is a late sign of hunger so offer a breastfeed as soon as you see early feeding cues like fidgeting, rooting (head turning with an open mouth searching for the breast) and sucking fingers and fists. If you’re worried that He Can’t Be Hungry He Only Just Ate! He can!
It is normal for some babies to cluster feed i.e. they seem to want to feed all the time at certain times of the day, for example during the evening and during growth spurts. The closer together the feeds the higher the fat content of all the milk and the higher its calorific value.
Remind a sleepy baby to breastfeed
You may need to remind a sleepy baby to feed every couple of hours or 10 to 12 times in 24 hours. Hold him skin-to-skin and encourage latching on during periods of light sleep and as soon as he begins to wake. Use breast compression (gentle breast massage during a breastfeed) and switch nursing (swapping breasts as soon as milk flow slows) to keep him feeding. For more tips see Breastfeeding a Sleepy Baby.
The following six minute video from Global Health Media summarises the signs that indicate your baby is getting enough milk. It shows clearly the type of active swallowing to look for when your baby is drinking well at the breast.
Is my baby getting enough milk?
There is a handy checklist in the Womanly Art of Breastfeeding explaining how to know whether your baby’s doing well:
How to Know Your Baby’s Doing Well
Weight gain. Look for a return to birth weight by two weeks. An average gain after that is roughly 1 ounce (30g) a day, but your baby may gain somewhat more or less.
Diapers. Look for at least three “okay” (thumb and forefinger circle size) diapers each day during the first month or so.
Your breasts. Look for comfortable nipples, a milk release within a minute (usually much sooner), and noticeable softening by the end of most nursings.
Nursing behaviour. Look for open eyes when the feed starts, periods of slow (about one per second) sucks with periodic pauses and finishing within a half hour at most feeds.
Disposition between nursings. Look for the baby falling gently asleep toward the end of the nursing (or contentment for at least a while before he nurses again), limp hands, and an unworried expression most of the time.
What doesn’t matter. How many minutes on each breast, whether he falls asleep at the breast at the end of the feeding, or whether he nurses long enough to “get to the hind milk”.
There are many ways to check whether a breastfed baby is getting enough milk, from weighing your baby to counting dirty nappies and more. If you are worried that your baby is still hungry, or not gaining weight, the article Understanding Your Baby’s Weight Chart may be helpful. There are lots of ways to increase your breast milk supply even if supplements are needed for a little while.
