UGHHHH!

We've been working with Caleb (and Isaac) on picking up their toys when they are done with them. Isaac is pretty good at helping, although he always finds something else to get out while he's cleaning up. Caleb seems to have no concept about what it means to clean up. We have to tell him item, by item, what to pick up and where to put it. Their bins of toys were taken away days ago because Caleb was warned if he didn't pick up, they'd be gone. He couldn't care less. (It doesn't help that he has 10X more toys that weren't in the bins...) Every night is a struggle to get the play room/living room even partially picked up.

This AM, I told Caleb that if he didn't pick up the toys, we were not going outside today. He looked at me and said, "Oooooh! Bummer!" Nice, huh?!

I think we've just let him get away with it for so long and now he thinks it's a joke and we'll eventually do it (which we do!) Any suggestions? We've tried making it a game/competition. We've obviously tried taking toys away. We've tried consequences (no playing outside, no going to the store, etc). We've tried showing him (them) how to pick up. We're pretty much at a loss at what to do.....bummer!!
