Object permanence is the understanding that objects still exist even when they cannot be seen, heard or touched. Rudy's mother hid the knife in her apron pocket and Rudy, being a baby, did not have the concept of object permanence which is why he stopped fussing about the knife once it was out of sight. It was no longer in his visual range and hence, he forgot about it.
