I was sitting in the porch with my son when I saw him start to take cans out of the recycling bins. I was about to stop him when I realized he was just placing them on the top of the electric fireplace. Then I realize he'd trying to get ones of all one colour (so he started with 3 gray barqs cans) then he tried to place them in pattern (so 1 gray, then 1 red coke, then 1 gray) when he couldn't reach another coke can he grabbed a black can and started group the cans by colour.

Then my husband came in & took the cans away laugh

Lucas is only 17 months old. I'm quite sure I know what behaviour like this generally means for the future.

Can anyone think of something else I can give him to try to replicate this with out giving him cans? (which are sharp & dirty).

I've never seen him do this with his blocks.

I'm not worried about diagnosis him with anything, I just want to make sure it wasn't a complete fluke. *sigh* my special little boy!
