My parents got Ethan the calculator for Christmas because we had been telling them how much he liked “nubbers.” Just recently, he started searching for it at bedtime and taking it to bed with him. I guess “some kids have a teddy bear,” and some kids have a…calculator? It has a screen that flips up, so I tried to flip it up while he was in bed so he could see it better. His response? “No touch, Daddy! My nubbers!” and he flipped it back down.
