My daughter loves junk mail, newspapers, ads, catalogs, post cards, anything addressed to "Current Resident" the child loves it all! This child has hundreds of dollars in toys, but her greatest joy is to sit on the living room floor surrounded by piles of junk mail. As I type she is currently investigating what is on sale at Albertsons. Sure eventually things get mangled or ripped up, but there is always a steady stream of new "toys" coming in the mailbox. No, she isn't embarassed, she just doesn't like the flash on the camera.
The teacher in me says it is positive because it allows her exposure to various forms of print. The Mom in me is just happy that something entertains her for 15 minutes!
