Nolan has just started drawing things that actually (or somewhat) look like the things he says. Even when it's a scribble, he'll scribble some eyes and mouth and it is actually looking like eyes and a mouth.
So when he asked me to take out an apple so he could draw it I was shocked to see a circle with a line at the top (or an apple with a stem). Then he asked for a pear which was more oblong with a line/stem. Then I took out a banana that was laid on it's side and he drew that too.
And then he asked for more so I grabbed an onion. He even drew the roots. I'm pretty impressed by this sudden skill he's picked up. He also has been writing letters correctly which is really amazing to watch his development.
