I've always called these "busy boxes" although the front of this one calls it an activity centre. Late sixties and early seventies Fisher Price was the BEST. Fun graphics, great colours, sturdy construction and most of all, what my Mom would call "play value" (the lack of "play value" was why I never got a lite brite for Christmas).
I'm going to try and keep the small person's world mostly free from toys with batteries, not because I'm against modernity or anything, but just because all those electronic sounds make me really crazy and I believe that children learn more from interacting with something than from pushing a button and being entertained.
And all babies need to learn how to dial a rotary phone, right?
