See the hole for the handle on the bench up there? Mom has decided that it is fun to pour stuff in there. Water, chocolate milk...
I usually try to keep a cup of water or other drink available for her at all times. If she is thirsty, she can just find it and drink whatever she wants. She won't (can't) ask for it, usually.
What is the solution? I don't want my floors ruined by standing water, but I also don't want Mom going thirsty. Keep small amounts of water available, so that if she does pour it down the bench handle, it is just a little bit? Check the floor every hour? Argh!
