A couple of nights ago, Geoff left the boys' bedroom during bedtime, and returned to find Nat reading Thomas a book. They were most of the way through. Geoff took over, and Nat corrected him when he added an extra word.
Also, Thomas went to the Toronto Zoo with Geoff's dad and stepmom on Monday, and brought home a map. Nat pointed out the African Savanna part to me. I asked him if he'd read those words on his own? Yeah, of course, Mom. Can I go rest on my laurels now? Really? There's something completely magical about having taught a child to read, to really read.
