OK, with Gary I told him it was just like medicine, he had to eat it. Then I found the tiny bottles of the flavored drinkable yogurt and he liked that better. Dannon has some and Activa is a drinkable yogurt. There are probably others too. Some of them are so tiny that you can drink them in one swig. I think if Gary was having that much trouble with his bowels, I would just insist he take it like medicine. But then, he probably is not as stubborn as your mom.
