Feeding challenges are one of the most common concerns new parents face. When it comes to how long does baby food last, here is what the guidelines recommend.
The short answer
Opened store-bought baby food lasts 1-3 days in the refrigerator depending on the type. Homemade baby food lasts 24-48 hours refrigerated and up to 3 months frozen. Once baby has eaten directly from a container, discard leftovers as bacteria from saliva can grow. Always check for signs of spoilage before serving.
Key takeaways
- Opened store-bought baby food lasts 1-3 days in the refrigerator depending on the type. Homemade baby food lasts 24-48 hours refrigerated and up to 3 months frozen. Once baby has eaten directly from a container, discard leftovers as bacteria from saliva can grow. Always check for signs of spoilage before serving.
- Usually normal when: You discard opened baby food after the recommended storage time
- Call your doctor if: Baby shows signs of food poisoning such as persistent vomiting, diarrhea, or fever after eating stored food
- Varies by age — see the age-by-age breakdown below
“The AAP recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, for 2 years or beyond.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to CDC, AAP guidelines, opened store-bought baby food lasts 1-3 days in the refrigerator depending on the type. Homemade baby food lasts 24-48 hours refrigerated and up to 3 months frozen. Once baby has eaten directly from a container, discard leftovers as bacteria from saliva can grow. Always check for signs of spoilage before serving. At 0-3 months, not applicable as babies are not eating solid foods yet. It is generally considered normal when you discard opened baby food after the recommended storage time. However, you should contact your pediatrician promptly if baby shows signs of food poisoning such as persistent vomiting, diarrhea, or fever after eating stored food.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Not applicable as babies are not eating solid foods yet.
4-6 months
When starting solids, you will likely use small amounts at a time. Spoon a portion into a separate bowl rather than feeding directly from the jar. This way, the remaining food can be refrigerated and used within 1-2 days for store-bought or 24-48 hours for homemade.
6-9 months
As baby eats larger portions, proper storage becomes even more important. Meat-based baby foods should be used within 1 day after opening. Fruit and vegetable baby foods last 2-3 days. Freeze homemade food in ice cube trays for convenient single portions.
9-12 months
With more variety in baby's diet, keep track of when foods were opened or prepared. Label homemade food with the date before storing. Discard any food that has been sitting at room temperature for more than 2 hours.
12-24 months
Toddlers eat family foods that follow standard food safety guidelines. Refrigerate leftovers within 2 hours and use within 3-4 days. Frozen leftovers should be used within 2-3 months for best quality.

Is Reheating Baby Food Safe?
Reheating baby food is safe when done properly. Reheat food to at least 165 degrees Fahrenheit (74 degrees Celsius) to kill bacteria. If using a microwave, stir well and test the temperature before serving to avoid hot spots. Only reheat food once. Never reheat food that baby has already eaten from, as saliva introduces bacteria.
Is My Homemade Baby Food Safe?
Homemade baby food can be a safe, nutritious option when prepared with proper food safety practices. Key guidelines include washing hands and surfaces thoroughly, cooking foods to appropriate temperatures, storing properly in the refrigerator or freezer, and being aware that certain vegetables like beets and spinach should be avoided for very young babies due to nitrate content.
Formula Storage Guidelines
Prepared infant formula can be stored in the refrigerator for up to 24 hours and should be used within two hours once at room temperature or within one hour after a feeding has begun. Opened containers of powdered formula should be used within one month and kept in a cool, dry place. Following these guidelines helps prevent bacterial growth that could make your baby sick.

When to Introduce Allergens to Baby
Current guidelines recommend introducing common allergens (peanut, egg, cow's milk products, tree nuts, wheat, soy, fish, shellfish, sesame) starting around 4-6 months when your baby is developmentally ready for solids. The landmark LEAP study showed that early introduction of peanuts (by 4-6 months) reduced peanut allergy risk by 80% in high-risk infants. Do not delay allergens - the old advice to wait until 1-3 years has been reversed because early exposure actually prevents allergies.
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
When Does My Baby Need Amino Acid Formula?
Amino acid-based formulas (also called elemental formulas) are prescribed for babies with severe cow's milk protein allergy, multiple food protein intolerances, or conditions like eosinophilic esophagitis who cannot tolerate standard or extensively hydrolyzed formulas. They are the most hypoallergenic formula available because the proteins are broken down into individual amino acids, making allergic reactions virtually impossible.
