Puzzle Mania

LittleMan has grown fond of puzzles.  Especially anything with a boy theme, like a train or a car.  In an attempt to foster this interest, I've been buying puzzles for him every couple weeks.  Unfortunately I haven't been able to find any good ones that are his level on craigslist.com yet.  So I've just been purchasing fresh ones.
So, yeah, he loves floor puzzles.  The first one we got was a Melissa and Doug bug floor puzzle, then we got a fish floor puzzle, then a dinosaur floor puzzle, and the latest one is a Thomas and Friends floor puzzle.  If he sees one of the boxes around, he is compelled to take the pieces out and put it together.    Each new one is slightly more challenging.  It takes him a while the first time; each subsequent time he is faster.  It is so neat and incredible to watch.  And it has actually turned out to be a great way to teach him vocabulary.  He loves naming all the different types of bugs in the bug puzzle, and the dinosaur names: brontosaurus!  And he is picking up some positive reenforcement phrases.  Like today when my mom came home and brought in the mail he said, "I'm so proud of you!"  
When I was making dinner, "you can do it mom!"
It is pretty cute.
