The Bugaboo of Boredom

Conventional parent-teacher wisdom says you're supposed to rotate the toys and books every four to six weeks, but I feel like I need to be doing that every four to six days! I have lots of toys and activities and books and videos available for the kiddo, but it's so hard to find something that he'll keep coming back to. There's that "zone of proximal development" and man is it hard to stay on target right in that zone. Simple lumps of play-dough aren't interesting to him, but he's not quite able to manipulate more advanced toys like the play-dough fun factory! I'm not complaining--I have lots of fun coming up with diversions--but it's recently occurred to me that seeing as how J isn't even two yet, I might have a long road ahead of me when it comes to keeping the little guy's brain busy!
