Last week, I went to get the "little books" his teacher sends home out of Russell's backpack, and while I was doing that, I found a package of white stuff marked "Borax powder -- add a little water to make crystals." He'd recently brought home something with a layer of crystals, so I guess she provided some extra for them to use at home. I put it out of Silas's reach and went back upstairs with the books.
After Russell read them and we did all the rest of the nightly routine, I was lying down with him to try to settle him into sleep. We had grown quiet, and he was so still that I thought he was asleep.
Suddenly he stiffened and looked at me with big, serious eyes and asked, "Mom, when you got the books out of the backpack, was my thorax powder in there?"
