Edan is starting to get on my last nerve. Not only is it annoying for me but its bad for his health. Edan has started to drink out of cups and glasses that are sitting on tables. usually it is water or coffee but im afraid hes going ot get into alchol or chocolate milk or something. He only does it when we step away for a minute, like i went from the living room to the kitchen to throw a pizza in the oven and the 30 seconds it took me by the time i got back my coffee cup that was 3/4 full was empty. i never catch him doing it so i cant tell him no so how do i get him to stop?
