Ugh! @amdeemer I say that because we are currently in week 2 of a 10 week food trial and my baby is miserable. However the short answer to your question is yes. His stool did get significantly firmer as well as the frequency of his needing to go #2 has dropped to a more manageble number! Now, if our dermatologist could just figure out what he is allergic to so he would stop itching his face and making it bleed everyday I would be the happiest person on the planet! But to the vet's credit that told us that about the grain free..I did notice Patton was visibly uncomfortable when he had to go #2 while on the grain free food and now he is not. Progress.
