Before Keane had his afternoon nap, I gave him a 10 minutes dinosaur stickers activity.
After a brief demo from me, Keane began to peel and paste the stickers by himself, with a little of my help. :) Keane was so excited and satisfied with his work that he wanted to bring it to bed... (-_-").
I wouldn't allow of course... I distracted his attention by going chanting and showed him a book on dinosaurs... After about 30 minutes, Keane finally went for his nap.
