If you have been using a pump to express and breastfeeding around the clock, you probably feel that wasting breast milk should be a crime.

It feels awful to have to throw away extra breast milk, in any amount. But babies have a tendency to not finish their entire bottles! It can be hard to figure out exactly how much they will take at each feed.

So next time you are considering throwing away a half-drunk bottle of milk, consider these ideas for how to use your milk instead of throwing it away.

In this article, I am going to cover the difference between expired breast milk that is no longer safe for eating or drinking (like milk that has sat out for too long, or is leftover in a bottle) and what to do with excess breast milk, like a freezer stash.

What Is Expired Breast Milk?

what to do with extra breast milk

Expired breast milk is milk that is no longer considered safe for your baby to drink.This would typically be if a bottle of expressed breast milk has been left for too long without being frozen.

Another reason for expired milk is if you have defrosted some milk for your baby to drink, and they didn’t drink the whole bottle. This milk should be consumed within 2 hours, and if it’s not, it should not be given to your baby.

Reasons Why You May Have Expired Breast Milk

  • You have high Lipase
  • Your baby didn’t finish the bottle and you have leftovers
  • You thawed too much milk and the fridge storage time period has elapsed.

Luckily, there are plenty of uses for expired breast milk, you just can’t feed it to your baby and you probably shouldn’t consume it yourself. And If your milk has spoiled it must be thrown away immediately.

What Is Excess Breast Milk?

Excess breast milk is the leftover breast milk in your freezer stash that is more than what your baby needs, or more than you can store.

If you have a strong supply and have filled up your freezer with expressed breast milk you will know what I mean!

You might end up with a huge freezer stash of breast milk if your baby has weaned early, or if you started giving formula instead of breast milk, or possibly if your baby has returned to full time breastfeeding.

How To Know If Your Breast Milk Is Spoiled

Like cow’s milk, breast milk that has spoiled is not safe to drink. You can easily tell if your breast milk has gone off because it will smell terrible. Off breast milk smells rancid. If you have concerns that your milk is no longer fresh, do not feed it to your baby.

Creative Uses For Expired Breast Milk

Once breast milk has been left out, it shouldn’t be consumed by your baby. These DIYs are perfect for milk that can’t be consumed. Please only add fresh milk that hasn’t expired or excess frozen breast milk to your baby’s food.

Breast Milk Baths

A breast milk bath is a great way to soothe and protect your skin. Not only does it have natural antibacterial properties, but it also contains nutrients that can help to nourish your skin. If you’re looking for a way to pamper yourself, a breast milk bath is a great option.

How To Make A Breast Milk Bath

To make a breast milk bath, all you need is some warm water and expired breast milk. Pour the water into a bathtub or large bowl, and add enough breast milk to make the water cloudy.

The benefits of breast milk baths are numerous. Not only will your skin feel softer and smoother, but you’ll also enjoy the natural antibacterial properties of breast milk. If you experience any dryness or irritation, it will help to soothe the symptoms.

Many people recommend using this type of bath for babies who are experiencing diaper rash, cradle cap or other skin irritations. The nutrients in breast milk can help to nourish and repair your child’s skin.

Breast Milk Lotion

Did you know that not only is breast milk full of antibacterial agents but it is also soothing for your skin? This simple breast milk lotion is great for calming eczema, acne, diaper rash and dry skin that you or baby might experience.

How to make breast milk lotion

  • 6 tbsp coconut oil
  • 1 tbsp beeswax
  • 3-5 drops of Vitamin E oil
  • 6 tbsp fresh breast milk, at room temperature

Using a double boiler or a saucepan on a very low heat, melt the beeswax and oil until the beeswax is almost completely melted, and remove from the heat.

Add 3-5 drops of vitamin E oil.

Add the breast milk to your oil mixture and mix to emulsify. You can use a whisk or an immersion blender to completely mix the ingredients together.

Transfer to a storage container. The lotion will thicken as it cools. If it seperates, you can use the immersion blender to whip it again.

Tip – I actually find it better to allow the mixture to start to set before blending with an immersion blender.

Store in the fridge, and use within 3 months.

Breast Milk Jewelry

Breast milk jewelry is a unique and beautiful way to keep your child close to your heart. You can choose from a variety of different pieces, including necklaces, bracelets, and earrings.

Most breast milk jewelry is made from the mother’s own milk. The jewelry is made by mixing the milk with resin, which helps to preserve it. Many companies that offer breast milk jewelry also allow inclusions, including hair, placenta and even ashes.

Breast milk jewelry is very sentimental. It’s a great way to keep your child close to you even when they’re not with you.

If you’re looking for a unique way to commemorate the time you spent breastfeeding your child, this is it!

Eczema and Dry Skin

Studies have shown that breast milk is as effective as steroid ointment for atopic eczema. You can apply it directly from the bottle onto your baby’s skin, or dip a cotton ball in some breast milk and use it to gently dab the milk onto your baby’s rash.

What To Do With Leftover Frozen Breast Milk?

If you have leftover milk that is still fresh, it is perfectly fine to eat. You may find yourself with leftover breast milk if you have defrosted too much for your baby to drink, or if you have a large freezer stash that you need to use up.

Other reasons that you may find yourself with leftover breastmilk include:

  • Baby weans
  • You return to exclusive breast feeding
  • You’ve left your milk in the freezer a little bit too long

Is Leftover Breast Milk Safe To Eat?

Of course, your freezer stash of breastmilk is completely safe to eat. Even milk that is past 6 month freezer time frame will usually be fine to consume, so long as it hasn’t spoiled. It’s really easy to tell if breastmilk has spoiled as it smells rancid!
