Usually blueish or clear, watery breast milk is indicative of “foremilk.” Foremilk is the first milk that flows at the start of a pumping (or nursing) session and is thinner and lower in fat than the creamier, whiter milk you see at the end of a session.
The more empty the breast, the fattier the milk. The fuller the breast, the lower the fat content of the milk. Therefore, milk that is expressed at the beginning of a nursing or pumping session tends to be more watery than milk expressed at the end.
Offer more frequent feedings.
Nursing more often prevents milk with a higher water and lactose content from building up in your breasts, so your baby takes in less lactose while she drinks. A gentle breast massage before a feed may also maximize the fat content of the milk if you're dealing with an oversupply issue.
You may notice your milk seems thicker and creamier towards the end of a feed. This is because, as the feed progresses, the fat composition gradually increases due to the mechanics of milk moving through the breast. It's often referred to as hindmilk, while the first more 'watery' milk is known as foremilk.
Watery breast milk is normal and usually not something to worry about. Some babies will have a foremilk hindmilk imbalance that can make them sick. Too much watery foremilk is usually corrected by completely emptying the breasts.
Too much foremilk is also believed to cause stomach and gastrointestinal (GI) issues in babies. The extra sugar from all that foremilk can cause symptoms such as gas, abdominal pain, irritability, crying, and loose, green bowel movements. 2 You may even think that your baby has colic.
For most mothers, breastmilk will gradually increase in fat content throughout the day. During the evening, young babies often cluster feed, taking in frequent feeds of this fattier milk, which tends to satisfy them enough to have their longest stretch of sleep.
Breast milk is typically white with a yellowish or bluish tint, depending on how long you've been breastfeeding. But the hue can change based on many different factors, and most of the time, a new color of breast milk is harmless.
A reliable way to treat foremilk/hindmilk imbalance is to separate your breast milk. Bottle feeding your baby less foremilk and more hindmilk will help them easily digest the lactose present in your milk.
Try pumping for longer intervals, ensuring that you experience letdown at each session, to make sure you're pumping enough to get to the good stuff. The other explanation for not seeing the hindmilk is that you actually have an oversupply of breastmilk.
After 10 to 15 minutes of the first milk, as the breast empties, the milk flow slows and gets richer, releasing the sweet, creamy hindmilk.
If your breasts are really heavy and full before your baby breastfeeds, hand express or pump for 1-2 minutes and discard your foremilk. Foremilk flows at the beginning of the feed and if your breasts are really full…. this milk can flow fast and furiously!
It's important not to give a baby thickened feeds unless advised by a doctor. Since gastro-oesophageal reflux disease can be associated with medical problems, exclusive breastfeeding (i.e. without any thickeners, etc) is advisable whenever medically possible.
Foremilk early in a pumping or breastfeeding session can be almost clear or blue compared to the creamier, fattier, yellowish hindmilk that comes later.
Milk production peaks by about a month after birth, with most of the increase happening in the first two weeks. Many mothers find it becomes more difficult – in some cases impossible – to increase the amount of milk they are making, after the early weeks.
There's no hurry to phase out night feeds. You can choose what works best for you and your child. For breastfed children, night weaning might be an option from 12 months. For formula-fed children, you can consider phasing out night feeds from 6 months.
The first few days: Your breast milk coming in
Around day three after your baby's birth, your breast milk 'comes in' and your breasts may start to feel noticeably firmer and fuller.
The sheer volume of milk and high sugar content often means babies gain weight very well with foremilk hindmilk imbalance—even though they aren't getting their “pudding”.
If you see bright green and frothy poop in your baby's diaper that almost looks like algae, they're probably getting too much foremilk – the low-calorie milk that comes first in a feeding – and not enough hindmilk, the higher-fat, super-nutritious stuff that comes near the end.
Hindmilk often appears thick and creamy and is richer and more calorie dense than the foremilk. There is no point in a feed where milk suddenly switches over from foremilk to hindmilk, instead the milk gradually transitions as the feed goes on.
However, if there is an overabundance of foremilk, the baby can consume it before receiving enough hindmilk. This is known as a foremilk-hindmilk imbalance, and it can result in gas, loose green bowel movements, and colic symptoms.
If you are concerned that the milk you're pumping doesn't have enough hindmilk, one way to increase it is to pump for longer so that you're pumping when your breasts are emptier. (Remember, the emptier the breast, the fattier the breast milk.)
Hindmilk is released after foremilk during a feed or pumping session. It is higher in fat and lower in lactose than foremilk. It has a creamier consistency and is whiter than foremilk. Like foremilk, hindmilk is also nourishing for your baby, but this denser milk may keep your baby feeling satisfied for longer.
Can I store foremilk that I pump off? You can and should save/store any excess milk you collect or pump off. If you're using the Haaka during feedings, or pumping a few ounces off an engorged breast and notice the liquid is thinner and more clear, this is likely foremilk. Foremilk is totally fine to feed to your baby.
