Why?

It is official! My daughter is in the terrible why phase. I think I might go crazy! I am not exaggerating when I say that she asks me why at least a hundred times a day. I answer one question and the immediate reply is why? Even when I say I don't know she asks why. Sometimes I think it is cute, but most of the time it is just annoying. I need to focus on being patient and hope that this phase doesn't last very long.
