If you’re breastfeeding or pumping, it’s very likely that you’ll experience a sudden drop in milk supply at one point or another. Maybe you’re dealing with it now?

There can be a number of reasons for this, which we’ll take a look at here. And luckily, there’s a lot you can do to get it back to normal.

Let’s dive in.

How does breastmilk work?

To avoid getting needlessly technical, breastmilk works on a supply and demand basis. Pregnancy triggers the initial supply of milk but, from there, it’s all about supply and demand.

Your baby demands the milk, and your body supplies it. This means that your body will continue to supply breast milk for as long as your baby suckles. Time is no factor.

All of that being said, a sudden drop in milk supply can still happen at any time, and for many different reasons. If you experience a sudden decrease in milk supply, there are ways of boosting milk supply fast. Before we look into that, let’s examine the reasons why a sudden drop in breast milk supply might happen.

Why does milk supply drop?

There are a number of common reasons for a sudden drop in milk supply. Once you know them, you can be vigilant about looking out for and avoiding them. Signs your milk supply is decreasing include:

  • An sudden increase in stress levels
  • Getting your period
  • A decreased amount of nightly sleep
  • A change in your diet

All of the above factors can easily contribute to a sudden drop in milk supply. In fact, if you’re a new mom and you suddenly experience a growth spurt, even that can cause a sudden drop in milk supply.

Signs that your baby might not be getting enough to eat

If you are concerned that your baby isn’t getting enough to eat, or getting the nutrients they require, there are three key signs to look out for.

Baby is not gaining weight or is losing weight

This is the first sign. If your baby seems to be losing weight, they are not getting the food and nutrients they need. This would strongly indicate a sudden drop in milk supply.

More subtle to notice is the fact that they are not growing and gaining weight in the way that you’d expect. They may not be losing weight but they’re not growing either. Keep a close eye on this. It’s a strong sign of low milk supply.

Too few wet diapers

It can be difficult to know how many wet diapers to expect. But, given how too few wet diapers is a strong sign of low milk supply, here is a handy guide from the Danish Health Authority (link in Danish). A baby should have this many wet diapers per day, according to their age:

  • 0-1 months: 8-10 diapers a day
  • 1-5 months: 6-9 diapers a day
  • 5-9 months: 6-8 diapers a day
  • 9-12 months: 6-7 diapers a day


This ties together with the above sign as well. If you notice that too few wet diapers are being made, and that your baby’s urine is a very dark color, they are likely dehydrated. They may also appear sluggish or drowsy. This is another key sign of a drop in milk supply.

Help for mom: What to do about it

If you suspect a drop in milk supply, and you’re wondering how to increase milk supply, there are quite a few different methods to consider and roads to take. Here are the most effective ways of addressing and tackling a drop in breast milk supply.

Talk to your doctor or a lactation consultant

This should be your first move. While there are drinks that increase milk supply, and you can also try acupuncture to increase milk supply (I’ll cover all of these below), visiting your doctor for advice on how to proceed should always be the first thing you do.

From there, you can try things like essential oils to increase milk supply, but see your doctor or lactation consultant first.

Skin-to-skin contact

Skin-to-skin contact between you and your baby is so important, even from a scientific perspective. According to Mayo Clinic, skin-to-skin contact releases prolactin and stimulates oxytocin which increases milk supply.

Never underestimate the power of physical contact between you and your baby. It does so much good, emotionally and chemically.

Breastfeed during the night

The hormones that stimulate breast milk production are produced in higher quantities during the night. So, a good practice to get into is breastfeeding during the night. This can really help counteract a drop in breast milk supply.

Try cluster pumping

Cluster pumping (sometimes referred to as power pumping) is a breast pumping technique that can help encourage milk supply. Over the course of one hour, you pump for ten minutes, take a ten minute break, then pump for another ten minutes, and repeat until the hour is over. You should do this once per day and see if it has a positive effect on breast milk supply.

Breast pumping

If you don’t use a breast pump at all, consider starting! Simply introducing a breast pump into your daily routine can have a strong effect on your breast milk supply.

Massage and warmth

Avoiding the cold can also have a positive effect on breast milk supply. Keep your body warm and your blood circulating. You can also try massaging your breasts to stimulate the flow of milk. A mix of warmth and regular massage can work wonders on the supply and flow of breast milk.

Smoothies for breastfeeding

Most of us know that smoothies can work wonders for getting us the nutrients we need. But there are specific smoothie drinks to increase milk supply.

If you’re interested in mixing up a drink to increase milk supply, these are the ingredients you need to be including in your smoothie: oats, chia seeds, flax seeds, nut butter, leafy greens, sunflower lecithin, brewer’s yeast, and milk dust powder. These ingredients are some of the best supplements to increase milk supply.


Acupuncture has been known to increase the supply of breast milk. It also has other health benefits for a new parent, including reducing anxiety and fatigue. If you’ve never tried it before, consider giving acupuncture a go as a way of increasing milk supply.

Essential oils

There are quite a few essential oils to boost milk supply, but the three most effective essential oils are fennel, basil, and clary sage. Using fennel to increase milk supply is a popular technique, and one that has been shown to have a positive effect; it’s a fantastic essential oil to increase milk supply. However, you should avoid peppermint.

When using essential oils, use what’s called a carrier oil to dilute the essential oils (coconut oil and almond oil work well). Apply 1 or 2 of these oils topically on the upper part of the breast 1-2 times daily. After 3 or 4 days you should be up to a good amount of milk.

This one feels like common sense but it cannot be overlooked (especially as a new mom). The simplest way is often the most effective: Rest when your baby is resting. Ignore housework and laundry; it can wait. What’s more important is that you rest when you get the chance. This can do wonders for helping with the supply of breast milk.
