Thanks, everyone!
He started drawing trains at 2. I vividly remember taking him to a Parents As Teachers playgroup. The kids were scribbling away and Tyler was humming along drawing a train. The teacher said, "Tyler, that's a TRAIN!
" He smiled and looked up at her like, "No kidding?!" LOL!
He has lots of drawing books and has taken lessons at Guy Gilchrist's Cartoonist's Academy, which fortunately, isn't too far away. He's getting a drawing tablet for Christmas. It'll be fun to see what he comes up with.
