Well zero has always got to lick the lids of my yogurt, but now since I've been on my diet, I've been eating lo-cal lo-carb using splenda... this wouldn't be a significant difference would you think? I figured not, but I just wanted to make sure. I just can't keep him away from my yogurt. He likes the shallow bowls of what I eat now, but he still gets it all over his chin and cheeks, it takes him ten minutes to clean up afterward!!
