Now I know, because I am a mom and I have eyes in the back of my head and exceedingly great powers of perception.
Today I found a book with a torn cover. The book is a sentimental favorite, so I said, “Oh Hannah, you tore Mama’s special book! That makes Mama sad! Tearing books is bad!”
I walked in to the dining room to see the poor dog sitting with pieces of torn book cover between her paws, and Hannah standing over the dog, shaking her little finger and saying, “Oh BAD! Bad bad!” She looked up at me and smiled brightly, probably convinced I would blame the dog.
Not bad for a 17 month old, eh? I have a hard time enforcing discipline when I am trying not to laugh.
