This last week has welcomes the development of putting objects In other objects. What shocked us is Marek knows where objects belong. So Marek takes the bath tub drain out (and empties the tub) and will then put the drain back in (or attempt to). Marek dumps all the dominos go out of the container, then he puts a few back in. He likes to drop objects from his crib down into the toy bin.

Of course he also likes to put things into places they don't belong. Drooping items through the baby gate and down the stairs is currently popular.
