Just as an FYI - not sure if it was Culturelle or contamination but the amount of uncontrollable diarrhea that DS1 had was unbelievable.
But this is where I also add that he was avoiding wheat, rye, barley, rice, oats, corn, dairy, soy, eggs, peanuts and tree nuts so his diet was ummm, strange. (Insane allergist who told me he wasn't gaining weight because he was eating foods he was allergic to - but if you test him via SPT and RAST, he will react to everything). Corn avoidance really gummed up the works because it is probably the most added allergen in the weirdest of places.
