Is Reheating Baby Food Safe?
The short answer
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.

By Age
What to expect by age
Not applicable as babies are not eating solid foods.
When warming cold purees, use a water bath or microwave in short intervals. Stir thoroughly and test on your wrist before serving. Baby food should be warm, not hot. Many babies also accept room temperature or cool food.
The same reheating principles apply. If microwaving, remove the lid, heat in 15-second intervals, and stir well between intervals. Always test temperature before serving. Discard any food that has been reheated and not eaten.
As baby eats more varied foods including meats and mixed dishes, ensure all reheated food reaches a safe internal temperature. Cut or mash reheated food as needed for baby's ability level.
Standard food reheating safety applies. Reheat leftovers once, heat thoroughly, and stir to distribute temperature evenly. Toddlers can eat food at various temperatures and many prefer room temperature food.

How Long Does Baby Food Last?
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.
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.
Baby Refuses Warm or Cold Food
Many babies and toddlers develop strong preferences for food served at a specific temperature. Some refuse anything warm, while others reject cold food. This is a normal sensory preference and not a sign of a feeding disorder. As long as your child is eating a reasonable variety of foods and growing well, temperature preferences are typically nothing to worry about.
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.
Could My Baby Be Aspirating During Feeding?
Aspiration occurs when food or liquid enters the airway instead of the esophagus. Signs include coughing or choking during every feed, a wet or gurgly voice after eating, recurrent chest infections, and breathing changes during meals. Silent aspiration can occur without obvious coughing. If you suspect aspiration, contact your pediatrician as a swallowing study can diagnose it.
