Expensive and disappointing

The Baby Gourmet cereals are the most expensive baby cereals compared to all others on the market, and yet very often, once you open the bag, you get that rancid smell. The cereal isn't expired but yet it seems that one of the grains or ingredients is old. My baby loved cereals until I switched to this brand. And I now realize that he probably can taste that it was rancid! I can say that out of the six bags we opened (brand new), three were stale. I keep all cereals in the same cupboard and only had this issue with Baby Gourmet. I stopped buying it and switched back.
