Beech-Nut Naturals baby food is made with real ingredients, gently cooked. Stage 1 Beech-Nut Naturals prunes baby food is a velvety smooth, easy-to-digest puree that's an ideal choice for introducing solids to your little one starting around 4 months old. We start with Non-GMO prunes and gently cook them with water over indirect heat to preserve color, flavor, and nutrients. This puree has a smooth texture and sweet taste that your baby is sure to love. All Beech-Nut baby food jars are vacuum-sealed for freshness. This jar can be stored in the refrigerator for up to 3 days after opening.
