As there are now several pages ready to go, I thought I'd better resolve how to stiffen the pages.
My conclusion is this: I'll purchase a large piece of corrugated plastic like the sheets used in the shipping office where I work. Once trimmed down to size, the plastic should offer enough stiffness so that Andy can manipulate all the items of his pages and I'll still be able to pop the pages into the laundry when needed without compromising the longevity of the page.
I'll make a pocket for the plastic to slide into by edging an activity page and a nursery rhyme page in bias tape, then use velcro or something similar to close the page before it is inserted into the binder.
