Yes you read that right my 21 month old. I can put it up out of reach and he will find a way to climb to it. So I started putting it in a travel mug where I can close it and him not be able to get to it. Well this morning he figured out how to take the top off and he poured it in his sippy cup and was drinking it. I dont want him drinking coffee, I can't bare him drinking coffee this is jsut not right, lol.
