I just got TOTW samples on Friday & although I couldn't find it on any of the literature, on the return address label it does say Diamond.
Princess loves it, has been eating it without any extra coercion or persuasion.

Of course that may change in a day or two

, but if it doesn't, not sure what I'm going to do yet. I was impressed that they sent 48 oz. of samples.
And no stinky poops, just smaller.
