Mrs Tea just posted about fingerpainting in a bag, but I can't do that with my toddler. He just tries to open the bag the whole time (and is surprisingly successful)! Once, a few months ago, I tried taping it to the table, and he just focused on taking the tape off. I tried to put together a marble shoot (with tp tubes) and he almost ripped them all off the wall before I could show him how to use it. He's driving this crafty mama crazy!
