Signs Your Milk Supply is Decreasing

It's natural for new mums to worry that they don't have enough milk to feed their baby. Not being able to physically see how much milk you're producing, combined with sleep deprivation and surging hormones, means second-guessing ourselves is inevitable.

The truth is, most mums will produce enough milk to support their baby's needs and it is very rare that they don’t. Read on to find out whether you really have a low milk supply and what you can do about it.

Sadly, due to a lack of support and knowledge, many women give up breastfeeding in the first few months. Research shows that less than half of babies are exclusively breastfed at three months old in Australia, with many women stopping because they believe their supply has decreased.

According to the Australian Breastfeeding Association, only a small percentage of women cannot make enough milk to support their baby's needs. These mothers genuinely cannot increase their supply due to physical issues, such as having insufficient glandular tissue.

So, the real reason most mums give up isn't due to their physical ability to supply enough milk for their baby. Instead, it comes down to a lack of support and information. That’s why understanding how breastfeeding works and what to expect is essential for all new mums.

How does breastfeeding work?

Your breasts begin to make milk throughout pregnancy. The first type of milk produced is called colostrum, which is yellow and has a thick consistency. Colostrum is super high in protein and antibodies, which helps to protect your baby from illness in the first few days.

Around day four or five, your 'milk comes in', and the colostrum transitions into mature breastmilk, which is white and much thinner. Around this time, it’s common for your breast size to increase drastically, and you will experience a sense of fullness.

Whenever your baby latches to your nipple and sucks, the hormones prolactin and oxytocin are released. These hormones are responsible for the production of milk, as well as the let-down reflex (the let-down reflex makes the milk in your breasts available to your baby as they suck).

Milk production works on a 'supply and demand' basis. So, whenever milk is removed by your baby or through pumping, a signal is sent to make more. However, it's common for women to see dips in their supply, where their milk production is impacted temporarily.

Why does breast milk fluctuate?

There are many reasons why a woman’s breast milk fluctuates. During these dips, women often assume their milk is drying up and decide to supplement with formula. But it’s the introduction of formula that has the potential to decrease supply. Because if you consistently miss a feed over several days, you start to signal that you don’t need as much milk as before.

As strange as it sounds, a dip in supply is a signal to feed more. When you feed more, your body receives the message that more supply is needed. And when your body receives the message that more milk is needed, you start to produce more milk.  

Signs of low milk supply

Your little one will let you know if they’re not getting enough milk. If bub doesn’t have 4-5+ wet nappies a day, isn’t gaining weight or isn’t meeting milestones, a low milk supply may be the cause. But before supplementing with formula, try some of the tips in this article.

If you're still concerned, seek advice from your healthcare professional. These indicators are relevant to older babies. If you would like information on milk supply and newborns, check out our blog: Is Your Newborn Baby Getting Enough Breastmilk.

Reasons why your milk supply might be low

You’re menstruating

You may notice a temporary drop a few days before your period arrives or when you’re ovulating. This is often due to a decrease in blood calcium levels. To combat this drop, you can take a calcium/magnesium supplement. Have a chat with your medical professional before taking any form of supplement or medication.

Your baby is distracted by the world

As your baby gets older, they become much more aware of the world around them. Sadly, those days where you could feed bub anytime, anywhere don’t last forever. If your little one is pulling off and feeds are regularly cut short, you may see a dip in your supply. In order to avoid a drop in milk supply due to baby distraction, try feeding in a dark, quiet room where distractions are limited.

You’re following a feeding schedule

The best way to support your milk supply is to feed on demand. This way, you know your breasts are draining and filling in unison with bubs hunger cues. However, if you follow a timing schedule, you risk allowing bub to get overly hungry, which can cause them to feed less efficiently and ultimately decrease your supply. If you’ve been following a schedule, try to loosen up and let your baby tell you when it’s time to feed.

Signs that don’t indicate a supply issue

Your baby is cluster feeding

Cluster feeding is normal and is usually due to your little one experiencing a growth spurt or just wanting to feed for comfort.

Your breasts no longer feel full

Your milk production will begin to regulate at around 6-8 weeks (or longer for those with an oversupply), and your breasts won’t feel as heavy and full anymore. Having soft breasts can feel very strange, especially for women who experienced engorgement. However, if your little one is still gaining weight and meeting milestones, your soft or ‘empty’ feeling breasts are not an indicator of low milk supply. Don't stress, all is well.

You’re not experiencing the let-down feeling

Many women report that their let-down reflex doesn’t feel as strong when their baby gets older, and some stop feeling it entirely. If this happens to you, take note of how your little one is sucking. You should be able to feel or hear them transition from quick sucks to longer, more drawn-out ones.

Your baby is waking to feed overnight

Due to misinformation, many new mums believe their baby should be sleeping through the night from six months of age. But all babies are different, and some take far longer to hit this milestone. Babies wake for several reasons overnight, including being too cold, overtired, under tired, for comfort or simply because they need assistance to transition through sleep cycles. Feeding your baby back to sleep is often the quickest solution, so don’t be afraid to make the most of this superpower while it lasts. As long as they are still gaining weight and meeting milestones, all is well.

Your baby isn’t pooping as often

Although your bub needs to have dirty nappies every day in the beginning, as they get older, it’s normal for them to go anywhere from two to ten days without a bowel movement. So instead, keep an eye on their wet nappies. Older babies should still be having 4-5+ wet nappies a day. Wet nappies are more of an indication of milk supply than poopy nappies.

How to increase your milk supply fast

Health is holistic, meaning there are a number of methods you should incorporate if you want to boost your milk supply: 

Breastfeed On Demand

That is, as often as the child wants. The number one way to increase your supply is to nurse more often. Our breasts produce milk in response to demand. So, you will naturally increase your milk supply by feeding more, expressing more, or combining both. If you've got the time, try a nursing holiday; this is where you cosy up on the couch, relax, watch a couple of movies and allow bub to feed as much as possible.

Power Pump

Power pumping is a technique women use to increase their milk supply. It mimics "cluster feeding’" a term used to describe when babies feed super regularly, usually during a growth spurt. Both power pumping and cluster feeding indicate an increase in demand and signal your breasts to produce more milk. 

So, how do you power pump? Basically, you pump for a set amount of time repeatedly with breaks in-between. For example:

  • Pump for 20 minutes
  • Break for 10 minutes 
  • Pump for 20 minutes
  • Break for 10 minutes
  • Etc

And you continue this for 1-2 hours. It’s a lot of effort, but it works. We recommend committing to 1-2 weeks to increase your milk supply. 

Try skin-to-skin

Research shows that by stripping down and making skin contact with bubs, you can increase your level of oxytocin, the hormone responsible for milk ejection. If you're expressing, you can boost your oxytocin levels just by thinking about bubs, smelling them (or an item of their clothing) or looking at photos of them.

Take care of yourself

Your energy requirements are significantly higher when you're breastfeeding. Your baby is relying on you for 100% of their nutrition. So, you need to try your best to eat enough healthy food. Aim for a wide variety of fruits, vegetables, whole grains, high protein foods and good sources of healthy fats. Drink plenty of water and rest (as much as you can).

Eat lactogenic foods (galactagogues)

The word lactogenic comes from the Latin word 'LAC', which means milk and 'GENIC', which means producing. You can incorporate certain types of foods into your diet, which will do exactly this, produce milk. Oats, yoghurt, almond milk, almonds, salmon and sweet potato are all great choices to add to your diet.

Introduce a lactation aid

The In-Shape Mummy Health Shake for Breastfeeding Mums is jam-packed with lactation aids, including organic milk thistle and organic fenugreek. Along with 25 minerals, probiotics and organic vegan protein to nourish you and your bub. These shakes are an easy and effective way to not only get the nutrients you need but also naturally boost your milk supply, especially when you're short on time. It's an all-in-one solution that tastes amazing.

The most important thing to remember is that our breasts are constantly making milk. But, factors like stress, tiredness and poor diet can decrease the amount. So, do your best to take care of yourself because you can't pour from a cup half full.

"I've lost 35 kgs thanks to the In Shape Mummy Health Shakes. 110 kgs to 75 kgs! Juggling two little boys under 2 years old doesn't leave much time for healthy choices for Mummy and the In Shape Mummy Health Shake is such an easy solution to get all the goodness I need to keep going! My older son is 20 months and I didn't get the chance to lose the weight gained whilst carrying him before I was pregnant again with baby #2. I easily gained 40kgs across the two pregnancies and no thanks to terrible pelvic pain in pregnancy #2 wasn't able to keep active. Now that my second son is here and the pelvic pain has gone I have stuck to replacing breakfast with my shake and walking every morning for the duration of the morning sleep. Some days I will do a second shorter walk during his nap. I'm still able to enjoy yummy healthy foods and definitely do not feel like I'm going without. I no longer crave sugary foods as the shake sets me up for the day with its magical satisfying ingredients! The shake has become even more of a must since returning to work! If I thought I was busy before, life just got a whole lot busier! Now that I've lost the weight, I have more energy, zero aches and pains and have a better mood. I tell all my friends about In Shape Mummy because easy weight loss doesn't need to be a secret! Xx"

"I discovered In Shape Mummy Health Shakes not long after my second baby was born. He has an intolerance to dairy so I was looking to find something that was safe for breastfeeding, and also vegan friendly. I have recently started a detox program with the help of a naturopath. She was so impressed with the ingredients that she has encouraged me to continue having it! In Shape Mummy has not only helped me lose the 26 kgs I put on in pregnancy, but it’s helped me nourish my body when I’ve been time poor and sleep deprived. It’s the only shake that I actually enjoy the taste of! My breakfast everyday includes ice, almond milk, water, a banana and my In Shape Mummy (my current fave is the caramel fudge!). At 11 months postpartum I feel great! And my breastfeeding journey is still going strong - my milk is in perfect supply for what Bub needs. I cannot recommend In Shape Mummy Health Shakes more highly!”
