I tried to think of something we might have around the house that we could stack up into a tower, when I realized we had just got a bulk purchase of tissue boxes. At first she had no interest, then she helped me stack, then, when I had knocked the tower over a couple of times ad she realized she could do it herself, wouldn't even let one box stand upright by itself.
We also let her play with the box from her new winter boots.
Unfortunately it's another case of the "drop what I'm doing so I can stare at the camera"s
Not a whole lot of excitement- this one's for you, Ellie.
