What to Do with Your Leftover Baby Formula?

If you're a parent, chances are you've ended up with leftover baby formula at some point. Maybe your baby has moved on to solid foods, switched formulas, or you bought more than needed. Instead of letting it go to waste, there are several practical and creative ways to make use of it.

This guide explores ways to repurpose baby formula, whether fresh or past its expiration date. From donating unopened cans to using expired formula for household projects, you’ll find plenty of useful ideas!

Can You Donate Baby Formula?

If the formula is unopened and within its expiration date, donating it is one of the best ways to help families in need. Here are some places that may accept unopened formula:

Food banks and shelters: Many organizations assist struggling families.
Women, Infants, and Children (WIC) offices: Some locations distribute donated formula.
Churches and community groups: Many host donation drives for baby supplies.
Parenting groups or online platforms: Facebook groups, Nextdoor, and similar communities can connect you with parents in need.

Always check with the organization first, as donation policies may vary.

What to Do with Expired Baby Formula

If your baby formula has expired, it’s no longer safe for consumption. However, you don’t have to throw it away! Alternative ways to repurpose it for household, gardening, and animal-related uses exist.

1. Household Uses

If the formula is expired but not spoiled (no foul smell or unusual texture), consider these creative applications:

Plant Fertilizer 🌱: Some formulas contain calcium and phosphorus, which can benefit plants when diluted with water.
Homemade Playdough 🎨: Mix expired formula with flour, water, and food coloring to create a soft, non-toxic dough.
Cleaning Solution 🧼: The mild acidity in the formula can help clean tarnished silver or work as a gentle household scrub.

2. Animal Use (With Caution)

While the expired formula isn’t safe for babies, some farm animals or pets might tolerate it. Always consult a vet first.

Livestock Supplement 🐖: Some farmers mix expired formula into pig feed.
Stray Animal Assistance 🐾: Shelters or wildlife rescues may use it for emergency feeding.

Everyday Ways to Repurpose Baby Formula

Milk Bath for Skin Care: Add formula to a bath for soft, moisturized skin.

How Long Does Baby Formula Last After Opening?

Once you open a container of baby formula, its shelf life changes, and proper storage becomes essential to ensure your little one gets safe and nutritious feedings. Different types of formula have different time limits for use after opening. Powdered formula—the most common type should be used within one month of opening. To keep it fresh:

Store in a cool, dry place.
Keep the lid tightly sealed.
Avoid moisture and heat exposure.

If you notice changes in smell, texture, or color, discard the formula.

Is It Safe to Reheat Baby Formula?

Warming up freshly prepared formula is safe, but reheating previously warmed formula is not recommended due to bacteria growth (check our blog on reheating formula). Follow these safety tips:

Warm formula only once: Discard any leftover formula after an hour.
Use a bottle warmer or warm water: Avoid microwaving, as it can create hot spots.
Store prepared formula properly: Keep it refrigerated and use within 24 hours.

DIY Projects Using Baby Formula

If you enjoy DIY projects, formula can be a surprising ingredient!

Homemade Playdough: Mix expired formula with flour and water.
DIY Glue: Formula can act as a binding agent in crafts.
Face Masks: Combine formula with honey or yogurt for a nourishing treatment.
