He hasn't lost it yet, and he won't let me put it in my purse or in the library bag. He kept it in his car seat "secret" cup holder pocket for a week. It's now inside on of his books on the table.
Today, he checked out books for the second time with it. He's getting so big...so grown up. I was gathering our coats and bag, and Karter of course, after story time. Kian had picked out about 8 books and wanted to use his card. I handed him his card to hold. I looked up and realized he had left the children's room and was at the desk. He had gone to the desk and put down his card and his book and checked out all by himself. So cute, and impressive, since at age five I would have been too shy to do that on my own. It's obvious he definitely feels proud and grown up with his very own card, and he told me he needs to bring his own bag for his own books next time. (And of course when we get home each week, he sprawls out in the doorway with all the books and reads them-all!-while I make lunch.)
