They are the most tasty and nutritious and also the most cost-effective. Wash all cooking utensils and foods before preparation. Steaming or microwaving fruits and vegetables is the most nutritious way to prepare the food. First foods can be pureed by adding some of the water used for steaming to thin the consistency. Store cooked foods in ice cube trays and when frozen, place in individual plastic bags for longer storage in the freezer.
Plastic containers work in the freezer too, but leave room for expansion as it freezes.
Label your food and the date to avoid guesswork. Defrost the baby food in the refrigerator in its container bag. Once food is defrosted, leave it in the refrigerator and reheat just the amount you intend to feed the baby. Never feed your baby from the container or jar if you plan to put it back in the refrigerator. The bacteria from the baby's saliva will spoil the unused portion of the food.
