What To Do With Expired or Undrinkable Breast Milk

It may be undrinkable, but please don't dump it!

That milk probably still has a multitude of soothing and healing properties.

What constitutes undrinkable breast milk?

1) stored milk that has been frozen too long

2) milk with high lipase or oxidization that causes baby to refuse it

3) fresh milk that has passed the safe window for consumption

Here are a few ways you can use breast milk that your baby can't/won't drink:

1) Milk baths. Breast milk baths can help with dry skin, cradle cap, rashes, eczema, the itch of bug bites, or just for general skin conditioning.

2) Breast milk lotion. It's easy to make, wonderfully soothing, and can help baby's eczema, diaper rash, baby acne, sensitive skin, even cuts and scrapes.

3) Syringes. Fill 1 ml syringes to save for first aid.

4) Dilution. If baby is refusing it due to high lipase (which is not actually harmful, it just tastes and smells off), try diluting it with fresh milk to lessen the undesirable taste.

5) Breast milk soap. If you're feeling extra motivated, make breast milk soap! Recipes below 👇

Milk Baths

Probably the most common way to use up undrinkable breast milk! Milk baths are super soothing and can help clear up cradle cap, eczema, diaper rash, as well as moisturizing dry or irritated skin.

How to make your milk bath:

  • fill baby's bath as usual
  • add enough breast milk to make the water cloudy
  • let baby soak at least 5 minutes (or longer) and sponge milky water over their whole body
  • pat dry and seal in the benefits with a gentle moisturizing lotion or amplify the benefits further with breast milk lotion! 👇

Breast milk lotion recipe


  • 3 oz grapeseed or coconut oil (see note)
  • 1 tbsp beeswax
  • Few drops of Vitamin E oil
  • 3 oz fresh breast milk, at room temperature
  • a couple of drops of an essential oil (for scent- optional)


Heat the oil and beeswax together slowly until the beeswax has just melted (stovetop or ~3 minutes in microwave on LOW setting).

Add the Vitamin E oil.

Slowly pour in the breast milk while whisking the oil mixture rapidly to emulsify. The mixture should thicken a bit.

Leave to cool before transferring to storage container. The lotion will continue to thicken as it cools.

Store in a dark place at room temperature. Beeswax reacts to light, and will discolor over time with exposure.

Do not freeze.

Lotion can be used for up to 3 months.

Note: Using coconut oil may be slightly more beneficial, but it also comes out harder, since coconut oil is solid at room temperature. Grapeseed oil produces a more traditional lotion texture and feel.

Note: Please use only your own breast milk, as other women's milk may pass on bacteria that your baby may not have been exposed to yet, like strep or staph

**reminder: if your baby has eczema related to dairy allergy, do not use lotion from breast milk that contains dairy!**

Breast milk syringes for first aid

Fill 1 cc syringes with breast milk, and freeze in a date-labeled ziploc bag. Keep in mind the longer the milk has been frozen, the less potent the anti-inflammatory and anti-microbial benefits will be.

Pull a syringe out for spot treating the following:

  • ear infections
  • pink eye
  • insect bites
  • minor burns
  • superficial cuts/abrasions
  • diaper rash

...or any other minor irritation!

Please do not use breast milk on open wounds or sores.

Breast milk soap

You'll need to use a cold processed method, as heat destroys many of breast milk's benefits. Also, be aware the soap will take 4-6 weeks to cure. It's a more involved process than the simple lotion, but has similar benefits.
