Xander Reads to Me

At bedtime now, Xander will read 1-2 books to me.  He has gotten so good at reading.  He can do the three lettered words, two lettered, and many sight words.  He can even read complicated words like "birthday" or "kitchen".  When he reads a book to me, he will say, "I can do it" and he proceeds to read out loud to me, only stopping to whisper, "what does that say" to a few words.
