Nicholas has taken an interest in the letters of the alphabet lately. So there are often times that he sees a word on a shirt and points to the letters asking what they are. A few days ago was one such episode.
I was wearing a plain shirt, but it said Old Navy across the top. He pointed to each letter, repeating after me when I named it.
Nicholas: B (close enough)
Whenever you ask him the question Why, he always answers 'cuz. Obviously a 2 year old doesn't understand Y as a letter yet.
